Breathable, Stretchy, Weather-Resistant, and Durable for Alpine Climbing and Backcountry Skiing The Cirque III Pant is built for alpine exploration, featuring weather-resistant materials and an alpine-forward design set, perfect for 3-season use and a quintessential ally for the modern mountaineer. Crafted from a bluesign® approved nylon blend, the 90D stretch double weave fabric offers unparalleled abrasion resistance and breathability. Movement-mirroring stretch and articulated knees ensure freedom of movement while climbing, skinning, or descending. Thermoregulating ActiveTemp™ treatment on the brushed tricot-lined waistband adapts to the body's temperature, and an avalanche beacon pocket with clip secures critical safety gear. Gusseted ankle zippers and reinforced scuff guards allow the pants to fit over various boot shapes and sizes and protect from crampons and ski edges. The adjustable waist tabs ensure a perfect fit, and YKK® DWR-treated zippers alongside zip hand and thigh pockets keep essentials safe and dry. Specifically designed for climbing and backcountry skiing in the high alpine, the Cirque III Pant is a three-season mountaineering staple.
