A go-to for climbers and backcountry adventurers, its articulated patterning and stretch combine for freedom of movement, crossover chest pockets are easily accessed while wearing a harness, and the trim fit and streamlined design give it a distinct Arc'teryx aesthetic. Redesign includes an updated fabric with increased warmth-to-weight ratio and durability, a front liner for additional warmth, updated sleeve opening for easier on/off, and taped seams for a clean finish.
