men's base layers

Base layers are uber versatile and not just underwear. Wearing a base layer as a long sleeve for early morning ascents, your merino base can also be your go-to piece for tropical excursions because it breathes so well, wicks and retains heat only when needed. Base Layers are a good looking way to be prepared for anything, your next-to-skin foundation.
