The Ines Pant is cut from 100% merino wool, certified fully to the Responsible Wool Standard, for a baselayer that stays next-to-skin comfortable from first run to last. A wide elastic waistband holds a secure, slim fit against the body, so nothing shifts or bunches under a shell. What Our Gearhead® Experts Are Saying:"I wore these under my boot liners for six hours of lift laps and never felt the need to swap them out the next morning. The merino stayed fresh through every sweaty push up a bootpack, no rinse required."
