Arcteryx Vertices Hoody Womens Labyrinth A cold weather base layer, the Vertices Hoody uses air permeable, moisture wicking Torrent™ 170 polyester blend fabric to give performance stretch and more effective thermal regulation. The balaclava style hood can be used as a neck warmer or a hood that fits easily over the head and under a helmet, and the trim fitted, straight cut torso has a wide hem that hugs the core. Sleeves are lean throughout, and a zippered hip pocket stores essentials. Articulated patterning and gusseted underarms add freedom of movement. Redesign includes Torrent™ 170 fabric and an updated balaclava style hood.
