Classic All-Season Merino Base Layer Bottom

The foundational layer for every forecast.

The Classic All-Season Merino Base Layer Bottom is the "set it and forget it" solution for variable mountain conditions. Designed to serve as your second skin from the high heat of a summer glacier approach to the biting cold of a winter belay, it balances the natural thermal regulation of Merino wool with added structural durability. Unlike pure wool layers that can wear thin after a season of hard use, this bottom features a reinforced core that stands up to the abrasion of layering systems while keeping soft wool against your skin, ensuring you stay dry, comfortable, and temperature-controlled regardless of what the mountain throws at you.
