Fleece Vs Wool Vs Down: Which is Better and Pros and Cons

When dressing for cold weather, you have a number of insulating fabrics to choose from. Two of the most popular materials are fleece and wool. The best fabric for winter clothing depends on the weather conditions you expect, the activities you plan to do, and your personal preference. In this guide, I will outline the differences between fleece wool and explain which is better for a range of different conditions and use cases. I’ll also list the pros and cons of fleece vs wool. Finally, I’ll compare them to a third material, down.

In this guide, we’ll cover warmth, weight, breathability, protection from the elements, comfort, versatility, cost, and much more. This info applies to all kinds of fleece and wool clothing and gear including jackets, gloves, scarves, base layers, blankets, and more.

The main difference between fleece and wool is the materials that the fabrics are made of. Fleece is a synthetic fabric while wool is a natural fabric. Fleece is basically a synthetic version of wool. The processes used to manufacture the two fabrics are completely different.

Generally, fleece is the better choice for extremely wet weather and for those on a budget. Wool is the better choice for extremely cold conditions. It’s the better all-around material but it is more expensive.

I’ve worn both of these fabrics extensively while hiking, camping, and cycling over the years. Hopefully, this guide helps you make an informed decision about whether wool or fleece is the better material for you.

An Overview of Fleece

Fleece is a synthetic fabric. It is man-made in a factory.

Fleece is made from polyester. Polyester is a type of plastic derived from petroleum and various chemicals. The most common type of polyester used to make fleece is called polyethylene terephthalate (PET). Most fleece is made from 100% polyester.

During the remanufacturing process, polyester fibers are spun into yarn. The yarn is then tightly woven together into fleece fabric. This fabric is then brushed. The brushing process gives the fleece its distinctive soft and fuzzy texture.

Brushing also gives the fabric more volume. The extra volume increases the insulation qualities of the fleece. Slight variations in the manufacturing process can give the fleece different textures. For example, fleece can be thin and fuzzy or thick and matted in texture.

Different types of fleece can be made from a blend of fibers. Both synthetic and natural fibers can be used. For example, fleece can be made from a blend of polyester and cotton, spandex, rayon, wool, or recycled materials such as plastic bottles.

Blending polyester with different fibers gives the fleece different properties. For example, blending polyester and spandex makes a stretchy fleece fabric that works well in activewear. The fleece lining in jackets and pants is often made from a blend of polyester and cotton fibers.

Different types of fleece have different names. Sherpa fleece is made from 100% polyester. It has a fuzzy texture. It is commonly used to make jacket linings and hats. Polar fleece is a thicker type of fleece that is commonly used to make jackets and blankets.

Fleece comes in different ‘weights.’ The weight refers to the thickness or loft of the fleece. Most companies measure the weight with Polartec’s 100, 200, 300 scale. The higher the number, the thicker, warmer, and heavier the fleece is. The number represents the weight of the fabric in grams per square meter. For example, 100 weight fleece weighs 100 grams per square meter of fabric.

Fleece was initially designed to imitate wool. In other words, it is basically synthetic wool. It was introduced around 1974. The fabric is commonly used to make jackets, liners, hats, gloves, scarves, and fleece blankets. Fleece is sometimes referred to as polar fleece.

An Overview of Wool

Wool is a natural fiber that comes from the hair of animals. It has been used to make textiles for thousands of years. Most wool comes from sheep. Wool can also be made from the hair of other animals including goats, bison, llamas, alpacas, rabbits, camels, musk oxen, and more.

The wool grows out of hair follicles on the animal’s skin. Chemically, wool fiber is mostly composed of the animal protein keratin. This is the same type of protein that human hair is made from. The fibers are much finer than a human hair. Wool also contains a small amount of lipids.

Wool from different types of animals has different names. For example, merino wool is made from merino sheep hair. Cashmere wool is made from cashmere goat hair. Qiviut wool comes from musk oxen.

Wool is harvested from animals through the process of shearing. The hair is cut off with blade shears (similar to scissors) or machine shears (similar to electric hair clippers). Shearing does not harm the animal. Only the hair is cut. When the hair grows back, the wool is shorn again.

Sheep and other wool-producing animals are generally shorn once per year. Usually in the spring.

Shearing wool-producing animals is necessary for their health. Over thousands of years, these animals have been selectively bred for wool production. They are domesticated. If the wool is not shorn, it will continue growing and make the animal sick.

After shearing, the wool is separated, cleaned, and sorted. The wool is then spun into yarn. Spinning interlocks the individual fibers into a long strand of material.

This yarn is then woven into wool fabric. Wool provides natural insulation. The resulting fabric is warm and usually expensive.

Some types of wool are more valuable than others due to the natural properties of the animal’s hair. Where the animal came from can also play a role in the quality of the wool. Generally, wool made from finer hairs is more valuable because it feels softer to the touch.

Sheep’s wool can be used to make a wide range of garments including sweaters, hats, shirts, pants, socks, gloves, undergarments, wool blankets, and more.

Fleece Pros

1. Fleece is breathable

Both air and water can pass through fleece easily. Fleece also doesn’t absorb water very well. When you sweat, the moisture on your skin vaporizes and passes through the fleece and dissipates into the air. Moisture doesn’t get trapped in the fabric. As a result, you won’t get soaked with your own sweat.

Different types of fleece offer different levels of breathability. This is the case because the fibers are woven differently. Thick fleece with a dense weave doesn’t breathe as well as thin fleece with a looser weave. Air can’t pass through the dense weave as easily.

Thin 100 weight fleece allows for excellent breathability. Thick 300 weight fleece doesn’t allow for as much breathability. Sherpa fleece doesn’t breathe as well as microfleece. Heavier fleece is warmer but doesn’t breathe as well.

Some fleece jackets feature a waterproof outer layer or flame-retardant coating. These reduce breathability.

2. Fleece has moisture-wicking properties

Fleece wicks sweat away from your skin. This is achieved with short fibers that create a capillary action. Water passes through the fibers without being absorbed. Fleece has a low absorption rate.

After the moisture is wicked away from your skin, it evaporates away from the outside of the fleece. You’ll stay warmer when your skin is dry. Lightweight fleece wicks moisture slightly better than wool. Fleece won’t get heavy and waterlogged like cotton or down.

3. Fleece is quick-drying

If your fleece gets damp with perspiration or soaked in rain, it dries out quickly. This is possible for a number of reasons.

First, the fibers that make up the fleece are hydrophobic. They repel water instead of absorbing it. It takes less time for less water to evaporate away.

The breathability of fleece also helps it dry quickly. Air can pass through the fabric and speed up the evaporation of moisture that has accumulated.

The sweat-wicking qualities also allow fleece to dry faster. Moisture moves away from your skin to the outside of the fleece jacket. This moisture can more easily evaporate from the outside of the jacket.

This quick-drying property comes in handy while hiking in wet weather. During my Wonderland Trail hike, my fleece was the only dry piece of clothing I had after everything I got caught in a 6-day rainstorm. I had to sleep in it to stay warm enough during the night as my sleeping bag had gotten damp.

4. Lightweight

The average fleece jacket weighs between 8 and 12 ounces (about 226-340 grams). This is 4-5 ounces (around 110-140 grams) lighter than a comparable wool sweater.

When both materials are wet, fleece is significantly lighter because it doesn’t absorb as much water. This light weight makes fleece an excellent material for ultralight hikers. The light weight also makes fleece more comfortable to wear because it doesn’t weigh you down or restrict your motion as much.

The weight of a fleece jacket depends on the features and thickness of the fleece. Ultralight fleece jackets use quarter-length zippers and have no pockets or hood to save weight. Thinner fleece jackets are lighter than thicker fleece jackets. For example, a jacket made from 100 weight fleece weighs less than a jacket made from 200 or 300 weight fleece.

5. Fleece doesn’t absorb much moisture

When moisture comes into contact with fleece, it tends to pass through the fabric instead of soaking into it. Fleece can hold less than 1% of its weight in water.

This characteristic of fleece offers several benefits. First, the jacket will dry out faster because it doesn’t hold onto moisture. The jacket will also be lighter because you won’t be carrying around a bunch of water weight.

6. Affordable

Fleece is a lower cost fabric. You can pick up a basic fleece jacket for just $15-$25. A high-end fleece jacket from a major outdoor clothing manufacturer may cost $60-$120.

Higher-end fleece jackets come with additional features such as a full zipper, hood, pockets, adjustable cuffs, etc. Jackets made from lighter-weight fleece tend to be cheaper than jackets made from thicker fleece.

7. Fleece may be more ethical than wool

Fleece is a synthetic material that is made from polyester, which is a type of plastic. It is derived from petroleum. Fleece is not made from animal fibers like wool and down.

Vegan hikers may find fleece to be a more ethical material than wool or down for this reason. No animals are harmed in the making of fleece. If you don’t use animal products, fleece is an excellent insulation option.

8. Fleece is easy to wash and maintain

Fleece is a low-maintenance fabric. You can just throw your fleece in the washing machine with the rest of your clothes. You don’t have to use a special detergent or drying technique as you do with wool. That said, there are a couple of precautions you can take when washing your fleece to extend its life.

When you wash fleece, you should wash it in cold water on a gentle cycle to avoid pilling. Ideally, you should wash your fleece with powder detergent because it tends to be gentler than liquid. You should also never use fabric softener or bleach when washing fleece.

You do need to be careful while drying your fleece. Fleece doesn’t shrink in normal drying conditions but it can shrink when exposed to temperatures above around 150°F. Under extreme heat, the synthetic fleece fibers can melt. This would destroy the texture of your fleece.

9. It’s soft and comfortable to wear

Fleece is available in different textures. The texture depends on the blend of materials that the fleece is made of, the thickness, and the manufacturing process. Fleece is generally softer than wool. Many find it to be more comfortable to wear.

In my opinion, fleece is one of the most comfortable fabrics. It feels great against the skin. It’s very soft to the touch. This texture makes fleece material excellent for jackets and linings for clothes. It’s cozy.

Fleece doesn’t itch like wool. Because it’s a synthetic material, it doesn’t contain any allergens. This makes fleece an excellent alternative to wool for those with sensitive skin or allergies.

10. Fleece is warmer in some situations

The warmth of a fleece jacket depends on the weight or thickness of the fleece and its loft. For example, thicker and heavier 300 weight fleece is warmer than thinner and lighter 100 weight fleece. This is the case because thicker fleece has more loft. This means that there are more air pockets in the fabric that can trap heat and provide insulation.

Fleece can also keep you warmer than wool in wet conditions. This is possible because fleece dries faster than wool. When a fleece jacket or wool sweater gets soaked, it can’t provide much insulation. Fleece can dry out quickly once you get out of the rain. Once the fleece is partially dry, it can provide insulation again. This makes it a great choice f or light rain.

11. Fleece provides some insulation when wet

Due to the hydrophobic properties of fleece, the material can provide some warmth when it gets wet. It retains some loft which provides insulation by trapping body heat. Fleece performs better than down or cotton when wet but worse than wool in damp conditions.

When fleece gets soaking wet, it can’t provide insulation. One nice thing about fleece is that you can basically shake your soaked fleece jacket out in the air and it will dry enough to provide some warmth. This is possible because fleece doesn’t absorb much moisture.

12. More durable

Fleece is designed to be durable, long-lasting, and easy to care for. Polyester fibers are incredibly strong. They can bend many times without getting weak and breaking. Fleece is also harder to tear than wool. If you snag your fleece jacket on a tree branch, a hole is less likely to form. Fleece can also handle abrasion better than wool.

Mold and mildew aren’t a worry either as long as you hang your fleece up to dry when you return home. Moths and other insects are less likely to eat fleece because it is a synthetic material. The fibers also don’t really degrade over time either.

Fleece garments don’t require any special care or maintenance to maintain its shape and size. You can wash fleece many times without needing to take any precautions. You also don’t have to worry about shrinkage as much while washing and drying fleece.

Fleece does pill and wear thin over time but not as quickly as wool. Overall, fleece is more durable than wool.

Fleece Cons

1. Not Sustainable

Fleece is a synthetic material that is made from polyethylene terephthalate (PET). This is the same material that most single-use plastic bottles are made of. It’s a type of plastic that is derived from petroleum. Petroleum is a non-renewable resource.

Fleece also isn’t quite as durable and long-lasting as wool. This means you’ll have to replace your fleece jacket more frequently. This means more material ends up in a landfill. Fleece also doesn’t biodegrade like natural fibers.

One way to make fleece more sustainable is to wear fleece that is made from recycled materials, such as plastic bottles. This is often called eco-fleece.

Fleece made from recycled materials requires less raw petroleum and energy to manufacture. It also keeps plastic out of landfills. This makes it a much more sustainable material. Of course, It’s still not perfect. Another option is to buy a second-hand fleece jacket from a thrift store.

If you prefer to wear more sustainable clothing, consider wool, cotton, or down instead. These materials come from natural fibers that are renewable and sustainable.

2. Fleece is not environmentally friendly

Fleece can introduce microplastics into the environment. Microplastics are tiny particles of thread that break off of the fleece when you wash it. Many of these plastic particles are too small to be filtered out when wastewater is treated.

According to this recent study “on average 1,174 milligrams of microfibers are released from the washing machine. These microfibers then travel to local wastewater treatment plant, where up to 40% of them can enter into rivers, lakes, and oceans.”

These microplastics do not biodegrade like natural fibers. They may take hundreds or thousands of years to degrade.

After the microplastics make their way into the environment, they can be eaten by sea creatures and other wildlife. As they pass through the food chain, they become more concentrated. Eventually, the concentration of microplastics becomes toxic.

According to this article, microplastics can bind with toxic chemical pollutants. Microplastics act as a vector for these harmful chemicals. This further increases toxicity.

It is still unknown how microplastics affect human and animal health. If you’re looking for a material that is more environmentally friendly with similar properties to fleece, consider merino wool. It is a more environmentally friendly material.

3. It may not last as long as wool

Synthetic fibers like fleece can degrade more quickly than natural fibers like wool or down. After a couple of years of use and wash cycles, fleece begins to pill and wear thin.

This wear is mostly caused by abrasion. The fibers can only bend and rub against one another so many times before they start to break.

When the fleece starts showing signs of wear, it loses much of its insulating properties. Your fleece jacket might last 3 seasons while a comparable wool sweater might last 5 seasons.

You’ll have to buy a new fleece more often. This can end up costing you more in the long run. More fleece also ends up in the landfill.

4. Fleece develops odors easily

Fleece doesn’t have antibacterial or antimicrobial properties like wool. This means that fleece develops an odor more easily than wool. This odor can be caused by a number of factors including sweat, bacteria, and mildew.

This can be an issue for those who need to wear their fleece for multiple days in a row without washing. If you’re out hiking for several days, your fleece jacket will start to stink. Hanging your fleece to air out can help to reduce the odor until you’re able to wash it.

5. You have to wash fleece more frequently than wool

Fleece doesn’t have any natural anti-odor properties like wool. You need to wash it frequently to keep it smelling clean.

You’ll need to wash your fleece jacket after every 4-7 wears depending on the conditions you wear it in and your level of activity. To compare, you may be able to wear a wool sweater for 1-2 weeks before it starts to stink.

6. It’s bulky

Even though fleece is lightweight, it doesn’t compress very well. It is a bulky fabric. A fleece jacket takes up more space in your pack than a down jacket.

You can make your fleece jacket a bit more compact by storing it in a compression sack. Compressing fleece does not damage it.

7. It pills

Pilling happens when broken and worn fibers clump together into little balls. This is the result of normal wear and tear. It is mostly caused by abrasion.

Pilling is a common problem with many fabrics. Unfortunately, fleece is particularly susceptible to pilling due to its fuzzy texture. Every fleece will pill after enough use and wash cycles.

Pilling reduces the insulating properties of the fleece. Pilling also makes the garment look worn and kind of dingy. When pilling gets too bad, it’s time to buy a new fleece.

It is possible to prolong the life of your fleece by shaving the pilling off. This does remove material which makes your jacket a bit less warm.

8. Fleece is flammable and has a low melting temperature

Due to the chemical makeup, surface texture, and density of the material, fleece is more flammable than many other types of fabric. You don’t want to sit too close to a campfire when wearing your fleece jacket. If a spark jumps onto your jacket, you could catch fire.

Most fleece jackets are treated with a chemical fire retardant to make them less flammable. This is a safety requirement in many countries. Check your jacket’s label to see if it’s been treated.

Running your fleece jacket through a hot washing machine can also cause it to melt or shrink. Check the label for more information on drying your fleece to avoid damage.

9. Fleece may not be as warm as wool

The warmth of a fleece jacket depends on its thickness. Thicker fleece provides more insulation. Most fleece jackets are pretty thin. A fleece alone can only keep you warm down to around 45 degrees.

If you expect weather below freezing you’ll probably want to pack both a fleece and an insulated jacket. Wear your fleece over a synthetic or wool base layer. A fleece alone can only keep you so warm. Layering is the best solution if you expect cold temperatures.

10. When fleece gets wet, it doesn’t provide much insulation

Because fleece is breathable, water can pass through easily. As a result, fleece gets wet more quickly than wool. When your fleece jacket gets wet, it doesn’t provide much insulation. Wool, on the other hand, can still keep you warm when it’s damp.

11. Fleece generates static electricity

When the fleece rubs up against your body, static electricity builds up. This attracts hair, lint, and dust to collect on the garment. You may also experience static shocks more frequently when you touch metal objects. This is mostly just an annoyance.

12. Looks

Some people consider fleece to be outdoor clothing. Wearing fleece can make you look like a hiker, hunter, or fisherman. It isn’t very fashionable in the city. This really depends on where you live. In areas where outdoor activities are popular, wearing fleece may be common. If you don’t really care about fashion, then this point doesn’t really matter.

Wool Pros

1. Resistant to odors

Wool has natural anti-microbial and anti-bacterial properties making it resistant to developing odors. Body odor comes from sweat. Sweat itself does not smell. The odor is caused by bacteria on your skin that break the sweat down. The bacteria’s waste produces the odor.

Wool resists odors by absorbing sweat away from your skin. This keeps your skin dryer which discourages bacterial growth. As a result, you won’t produce as much body odor while wearing wool.

Wool fibers also bind to the odors that are produced and retain them in the fabric. As a result, the fabric stays smelling fresh longer. According to this study, “Fabrics containing 20% wool had substantially reduced odor intensity compared to 100% polyester.” The article goes on to say that “100% wool showed higher sorption capacity than the blends.” Wool effectively retains odors better than other fabrics. When you wash your wool, the detergent releases the odors.

This anti-odor property is helpful when you’re hiking for multiple days without a shower. It’s also nice for travelers who are unable to wash their clothes frequently. You can wear the same wool shirt or sweater for weeks without getting smelly.

2. Wool provides insulation when wet

Wool can absorb a lot of moisture before it starts feeling wet. It is a hygroscopic insulator. Water molecules get trapped in the porous fibers of the wool. They do not permeate the fabric. As a result, wool stays dry to the touch when damp.

The natural crimp of the fibers also prevents wool from losing loft when wet. Tiny air pockets remain between the wool fibers. These trap body heat, which keeps you warm.

If you get caught in the rain without waterproof gear, your wool sweater or base layer can still provide insulation. This property makes wool an excellent choice for hiking in wet weather.

3. Wool is breathable

Wool is slightly more breathable than fleece. It allows air to pass through freely. It is a naturally breathable material. Animal hair needs to be breathable so air can circulate through and dry the animal off if it gets wet or cool it down if it gets too hot.

This breathability helps you avoid getting soaked with sweat. When you perspire, the moisture can escape and evaporate away freely into the environment. It doesn’t get trapped against your skin. When you get wet in the rain, the moisture can also freely evaporate away. The breathability also helps you stay cooler in hot weather.

Wool is a more breathable material than fleece. It is one of the most breathable types of fabric used for making clothing.

4. Wool can help you regulate your body temperature

As you warm up and start sweating, wool fibers wick sweat away from your skin and absorb the moisture into the structure of the fibers. That moisture can then begin evaporating away. This helps to keep you cooler and dryer.

When you stop your activity, wool prevents rapid cooling by slowly releasing moisture into the environment. This helps to keep you warmer. You won’t experience that rapid evaporative skin cooling like you do when you wear synthetic materials, like fleece.

When you wear wool, your body temperature will remain more constant as you transition from active to inactive. You won’t suddenly overheat or freeze.

5. Warmer

Wool’s purpose in nature is to keep animals warm. It is a natural insulator. Wool is slightly warmer than fleece.

Most types of fabric keep you warm by trapping your body heat in small air pockets in the fabric. Some types of wool, such as merino wool, can actually generate their own heat. This helps to keep you much warmer.

This heat generation is possible thanks to a chemical process. When water is absorbed into the wool fibers, it passes through tiny pores. The hydrogen bonds of the water break down. This creates a chemical reaction that creates heat. This process is called adsorption. This phenomenon makes wool a particularly warm fabric.

According to this article “Experiments have found through this process, one kilogram of merino wool can produce as much heat over eight hours as an electric blanket.”

Fleece does not generate heat. It only keeps you warm by trapping your body heat.

6. It can keep you cooler during the summer

While hiking or traveling in hot and dry climates, wool can keep you cooler than synthetic fabrics or cotton. This is the case because wool wicks moisture away from your skin and allows it to evaporate away.

This is possible thanks to the moisture-absorbing properties of wool as well as the crimpy and curly shape of the fibers. If you’re traveling or hiking in a hot region, merino wool t-shirts are an excellent option.

Synthetics are also sweat-wicking. They just don’t perform quite as well as wool. Cotton absorbs moisture and holds it against your skin.

7. It’s quick-drying

Wool dries out faster than cotton or down but not quite as fast as fleece and other synthetics. It is a quick-drying material.

The time that it takes wool to dry depends on its thickness. The thinner the wool, the faster it will dry. A thick wool sweater is pretty slow to dry. A thin merino wool base layer dries quickly.

8. Wool is flame retardant

According to this study from the Handbook of Fire Resistant Textiles, wool has naturally flame retardant properties. It is difficult to ignite. If wool does start to burn, the flame tends to extinguish itself instead of spreading. When wool burns, it dissipates into ash. It doesn’t melt into hard material like synthetics. While wearing wool, you don’t have to too much about sparks from your campfire

9. Wool is a renewable resource

Wool is a natural fiber that is made from the hair of animals such as sheep. The animal’s hair continues growing throughout its life. Sheep are usually shorn once per year. The same sheep can be shorn many times throughout its life.

Animals are considered a renewable resource because they can reproduce quickly and infinitely. This is a major benefit of natural materials.

The petroleum used to make fleece is not renewable because it is finite.

10. Wool is an environmentally friendly material

When your wool garment wears out, you don’t have to worry about it polluting the environment in a landfill. It is a biodegradable and compostable material. Wool can biodegrade in just 3-4 months when it’s buried in the ground. It is a completely natural material.

Wool can also be recycled into other products, such as insulation. It can sometimes be recycled into other garments or textiles as well.

There is one type of wool that is not environmentally friendly. Superwash wools are coated in a layer of plastic. These take a long time to degrade.

Livestock farming for wool production also emits greenhouse gasses. Animal farming also takes up a large amount of resources including land, water, and feed. Wool isn’t the most environmentally friendly material but it is certainly better than fleece.

11. Wool is semi water repellent

Wool has a natural wax coating called lanolin. Lanolin is a substance that is secreted from the sebaceous glands of wool-producing animals. The lanolin helps wool repel water. This water repellent property is the reason that fishermen used to wear wool knit sweaters while out at sea.

Over time the lanolin can wear off. You can replace it by treating your wool garment with fresh lanolin.

Wool can also absorb about 30% of its weight in water before it starts to feel wet to the touch. This property of wool helps you stay feeling dry, even when the wool is damp. Only after the wool reaches saturation of 30% does it start to feel wet.

12. Wool is wrinkle-resistant

Wool is much less likely to wrinkle than cotton or linen fabrics. It is a popular choice among travelers for this reason. You can pack it tightly and not have to worry about wrinkles.

If your wool clothing does get wrinkled in your suitcase, you can dampen it in the sink or expose it to humidity from the shower then hang it to dry. When it dries out, it will be wrinkle-free.

13. Wool is compressible and packable

Wool compresses much better than polyester fleece. This makes it a great choice for those who like to travel with a carry-on bag only. You can easily fit 4-5 merino wool shirts in a standard-sized packing cube or compression sack.

This can save you a massive amount of space for other gear. You could also use smaller luggage. I recently replaced some of my travel clothing with merino wool for this reason.

14. It’s wind resistant

Due to the tight weave of the fibers, wool blocks wind better than synthetics like fleece. A wool sweater can keep you warmer under breezy conditions.

Of course, wool can’t replace a hard shell layer. If you expect cold winds, you’ll need something a bit more wind resistant than wool such as a rain jacket or windbreaker.

15. Wool is more versatile

A wool shirt can be worn year-round. Wool keeps you warm in cold weather and keeps you cool in hot weather. A thin wool shirt can be used as both a base layer or on its own as a regular shirt. Wool sweaters can be worn for outdoor activities as well as for more formal activities. For example, you could wear a nice wool sweater to work.

16. Durable and long-lasting

Wool fibers can bend up to 20 thousand times before failure. Wool garments tend to hold up well and last a long time with proper care. You should get 4-5 years of heavy use out of a quality wool sweater. A comparable fleece jacket may last a year or two less.

Having said this, wool can start to pill when exposed to abrasion. For more durability, consider choosing wool garments that are blended with synthetics. 85% wool is more durable than 100% wool.

Wool Cons

1. It is expensive

A nice wool sweater costs $1
