The base layer for extreme cold this mountain weight, single-face stretch base layer can also be used as a mid-layer in clothing for cold weather. Comfortable, soft, stretchy, and just what you need in frigid weather.

Why we like it:

This has a durable smooth outer face for easy layering that resists snagging (yea, we abuse our clothes… you expected anything else?) with a soft, brushed fleece, inside and some wind resistance, giving this incredible versatility.
