"What Our Gearhead® Experts Are Saying:""I took these into the gym on a humid day, and they were a lifesaver. The fabric is super light, dries fast, and stretches exactly where it needs to. The thigh pocket is actually usable mid-climb, and the waistband stays comfortable under a harness.""Warm rock and long afternoons at the crag ask for gear that keeps us moving easily, and the Mammut Sender Climbing Short does just that. Its lightweight recycled polyamide blend breathes well in the heat while offering the stretch we need to pivot, high-step, and twist into position on technical holds. A climbing-specific cut keeps movement smooth as we cycle through warm-ups and work on new problems. Useful storage sits neatly out of the way thanks to a zippered thigh pocket for tape or a small phone and two flap front pockets for relaxed moments between climbs. The elastic waistband adjusts quickly with a drawstring, giving us a secure fit that stays comfortable beneath a harness. When temperatures climb and our sessions stretch long, the Sender Climbing Short keeps things cool, simple, and mobile."
