What Our Gearhead(R) Experts Are Saying: "These baselayers are brilliant for ski touring-light, breathable, and quick to adjust when conditions change. The full side zips mean I can remove them mid-tour without touching my boots, and the silicone grippers keep everything in place under shells. They've become a go-to for big vertical days."We rely on the Raide TourTech Baselayer Bottoms to keep pace with changing mountain conditions. Built for ski touring efficiency, these 3/4-length layers feature full-length side zips that let us shed or add warmth on the move without removing boots or pants-a perfect solution for long ascents or unexpected weather shifts. The soft brushed interior feels comfortable against the skin, while the friction-free outer fabric glides easily beneath shells for unrestricted movement. Ventilation cutouts at the hips and calves regulate airflow when we're pushing for the summit, and the adjustable waistband ensures a secure fit all day. Finished with silicone calf grips and a beacon-sized pocket that doubles as a pack pouch, the TourTech Baselayer Bottoms make layering seamless from dawn patrol to the last lap.
