Women's Classic All-Season Merino Base Layer Bottom

The one layer that never leaves your kit.

The Women's Classic All-Season Merino Base Layer Bottom is the first thing you put on for a climb and the last thing you take off. Built with Smartwool’s Core Spun technology, it wraps Merino wool around a nylon core, giving you the durability to withstand seasons of use without losing the soft, temperature-regulating feel of wool against your skin. The mid-rise waist and flatlock seams are designed to sit flat under harness leg loops and shell pants, eliminating chafing during long days on the move.
