Important Facts for Base Layers

When it comes to base layers, leave the cotton at home. Instead of cotton, you’re going to want to pick up lightweight, synthetic fabrics or merino wool. The fabrics should dry quickly and be moisture-wicking.

Wool: A good option for heat retention and odor control, very breathable

Synthetics: Thinner and less warm, more durable and quick-drying

Silk: Comfortable, soaks up moisture

Be sure your base layers are lightweight because if you end up not needing them later on in the day, that weight will be added to your pack.

For Women

When in doubt, choose comfort. You’re essentially creating a second skin with base layers, so make sure they’re form-fitting but still comfortable.

A base layer set will keep you warm during cooler days. If you are particular about the way things feel on your skin, a set is a great option, because the fabrics will match and feel the same on your skin. If that isn’t an issue, feel free to mix and match your base layers. If you tend to run cold, choose something thicker on top, for example, this Kari Traa base layer top made of jacquard merino wool. You can also choose to go for something like a quarter-zip if you tend to warm up quickly. 

On the bottom, try something with a synthetic fabric that is moisture-resistant, like these tights from REI Co-Op. You’ll also want to make sure you have thick, wool socks that keep your feet warm. (Though socks are not technically base layers, they’re important to mention.)

For Men

Men should similarly pick their base layers based on their own personal needs. If you tend to run warmer, something that is part wool and part synthetic is a great option, because it’s still thick but has stronger moisture-wicking properties. If you need something thicker, this quarter-zip from Smartwool is a great option as well. 
Keep your legs warm by wearing a base layer tight under a comfortable pair of pants. This pair from Craft is entirely synthetic, meaning they’re a little thinner, but they’re a great option if it’s not a particularly cold day. For something warmer, choose apparel with more wool in it, like these tights from Smartwool.
