What Our Gearhead(R) Experts Are Saying:"I put these through a long bouldering session, and the freedom of movement was unreal. The fabric is light but durable, the waistband adjusts easily, and the thigh pocket is actually usable while climbing. They feel made for days when you're constantly changing positions on the wall."Warm rock, shifting body positions, and long afternoons at the crag call for a pant that moves as naturally as we do. The Mammut Sender Climbing Pant uses a lightweight, 4-way-stretch recycled polyamide weave that breathes easily while holding up to repeated contact with holds and rough stone. The climbing-specific pre-shaped cut helps us flow through high steps and twisting movement with less resistance, creating a smooth feel during both warm-ups and project attempts. Storage stays out of the way but close at hand, thanks to a zippered thigh pocket for small essentials and two flap front pockets for relaxed transitions between climbs. The elastic waistband adjusts quickly with a drawstring, and an internal hem drawcord fine-tunes the fit around our shoes. Whether we're bouldering in the shade or linking pitches on an evening route, the Sender Climbing Pant keeps comfort and mobility working in our favor.
