The Cirque III Pants are built for alpine exploration. Weather resistant, fully featured, and designed for three-season performance, they are a quintessential ally for the modern mountaineer. Crafted from a bluesign approved blend of nylon, polyester, and spandex, the 90D stretch double weave fabric offers unparalleled abrasion resistance and breathability, while the 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 bodys temperature, while the 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 secure waist with an adjustable embedded belt ensures a perfect fit, and YKK DWR-treated zippers alongside zip hand and thigh pockets keep essentials safe and dry.
