When you plan to go camping or hiking in such cold weather, you must ensure that you have everything you need to keep your body warm. And a base layer is essential for it. A good base layer should keep you warm while also acting as a second skin, keeping you dry and wicking away moisture quickly. Well, you don’t have to be confused about which one to choose as we’ve compiled a list of the top ten best base layers for extreme cold. Explore the features and materials, then select the one that best suits your needs.

Frequently Asked Questions (FAQs)

In case you don't know

What is the purpose of a base layer?

A base layer that acts as a second skin, protecting your real skin from cold and even the sun. It is a garment or layer that is closest to your skin and provides warmth while absorbing and evaporating sweat to keep you warm and comfortable.

What makes a good base layer?

A base layer should be snug enough to trap air next to the skin and insulate the body from cold temperatures. The cold is more likely to enter if there are gaps between the fabric and your skin, that's why it's better to choose a base layer size you normally wear because they are made slightly smaller with this in mind.

Can you wear two base layers?

Absolutely, yes. Wearing two base layers is socially acceptable, normal, and safe as long as you feel comfortable. It usually does while out in such cold weather since you need extra protection from the cold.

Is merino wool a good base layer?

Merino wool is high-quality wool derived from merino sheep, which are found primarily in New Zealand. It's a great fabric for active base layers because it's soft, breathable, moisture-wicking, and naturally odor-resistant. However, some brands combine it with other materials to increase the durability of the base layer itself, which is also something to consider.

I have been wearing my 150 baselayer for training for a mountain climb this May...The weight is perfect for under my soft shell and with my 50lb backpack...no drama with seams irritating me and having to shift around. Dries quickly and of course, doesn't smell like the synthetic pieces I have. I like it so much I bought it in a second color...would definitely purchase again.
