What do base layers even do?

As stated above, the purpose of a base layer is to elevate body temperature and remove moisture away from your skin. If you’re active, it’s normal for you to sweat, and during winter, this sweat can open you up to catching a chill. Base layers act as a second layer of skin, it’s the base of your outfit.

You’ll be able to have a mid layer and outer layers on top which are appropriate for the weather and climate you’ll be in.  So, if you’ll be outdoors during the winter, a base layer is an absolute necessity.

Types of base layers

There are a variety of different fabrics which can regulate body temperature and act as a moisture wicking base layer.

Synthetic fabrics and merino wool are some of the most popular materials used for base layers. Let’s take a closer look at the different materials used.

Synthetic base layers

Synthetic material is one of the most popular materials used for base layers. They’re usually made of polyester or a polyester blend. These layers will protect you from weather anywhere ranging from -8 to -10 degrees if worn with an outer layer.

What’s good about synthetic material is that it’s quick drying, lightweight and is excellent for moisture wicking. Though, it’s not antibacterial and not as warm as merino wool. But, unlike merino wool, in relation, synthetic material is much cheaper.

Merino wool base layers

Merino wool is a great natural way to regulate body temperature. What happens is that the tiny air pockets within the wool help to remove excess heat from your body, preventing you from overheating. However, at the same time, it also acts to retain heat as well.

You’ll be able to stay warm in temperatures dropping down from -15 to -20 degrees, at the same time, you can also wear merino wool in warm weather. In addition, it has natural UV resistance, so you won’t have to worry about any winter sunburns.

Merino wool is naturally antibacterial, highly wicking, and breathable. It’s an amazing base layer, however, it’s more expensive in comparison to synthetic and doesn’t wick as well as synthetic materials.

Bamboo base layers

Bamboo base layers are a relatively new concept in outdoor apparel. Though it’s made of bamboo, it can also include a combination of Lycra, merino wool and cotton. Bamboo base layers are generally a tighter fit and can hold their shape better

They’re also a soft material, so if you have sensitive skin, this is definitely the material you should be looking for.  There are a lot of great things about bamboo: it’s quick drying, antibacterial, antistatic, eco-friendly and resistant to abrasions. The only problem is, is because it’s new on the market, it may be a slight challenge to find.

Cotton base layers

We recommend that you don’t choose a cotton base layer. Cotton is not a wicking material, so if you sweat, you’re going to feel it.

In addition, when wet, cotton becomes very heavy. It may add some warmth, however, it’s incomparable to the other materials.

Who can wear a base layer?

  • If you’re constantly cold, wearing a base layer will help you retain heat regardless if you’re on the slopes or at the office. If you’re at the office, you can opt for a silk base layer, it’s more trendy,
  • If you’re a city cyclist, a base layer will help battle the annual elements – protecting you from both now and rain. For this, opt for merino wool due to its light weight and temperature regulating properties.
  • If you’re going skiing or snowboarding, you’re going to be going against cold temperatures. Merino wool will keep you dry and warm, Plus, you’ll be able to layer.
  • If you’re a motorcyclist, you’ll be in all types of weather, plus battling city traffic. You can get up to some high speeds, so you’ll need something to protect you from the wind chill. Getting a synthetic base layer will keep you warm and you’ll be able to layer appropriately with your gear.


There is one important thing to note about the fit of your base layer. Because it’s acting as a second skin, you want to make sure that it fits snugly. If not, it won’t be able to properly act as a wicking base layer, thus, you’ll stay sweaty. However, make sure that it doesn’t restrict your range of motion.

Now that you know about the materials available, what a base layer does, the fit and who can wear one, it’s time that you were shown the best base layers for women.
