With Merino wool's natural warmth, moisture-wicking, and breathability, this piece stands as the warmest in our midweight collection, ensuring you’re prepared for whatever lies ahead.

This legging showcases the unmatched qualities of Merino wool, a fine and soft wool that avoids the itchiness often associated with traditional wool. Merino provides warmth even when damp, offers natural odor resistance thanks to the wool's antibacterial properties, and is low-maintenance, requiring no special wool wash cycle.

Its flatlock seams reduce chafing during intense activities, allowing you to focus fully on the journey rather than any discomfort.
