The Best Long Underwear

Having a layering system is important in cold weather, and a good baselayer is a critical part of that. These thin, warm pieces sit next to your skin to preserve body heat, but allow you to move freely and help wick sweat away when you’re working hard. When choosing a pair of long underwear, consider the type of material, durability, and breathability.

Best all-around

Duofold Men's Mid-Weight Wicking Thermal Pant

Soft and breathable. This bottom leverages a cotton/polyester blend for optimal skin-feel and performance.

What We Liked

This baselayer’s 60% cotton, 40% polyester blend brings out the best of both materials. The cotton makes the fabric soft and breathable, while the polyester provides moisture-wicking and durability. Having a fly is always a nice touch, and the flat waistband should feel good even when worn beneath a backpack. Order Online.
