Down Composite Mapping strategically places synthetic insulation – made from bluesign approved polyester – in moisture-prone areas. 15D Arato outer is light, durable, made from 100% recycled nylon, and coloured with dope-dyed yarns, a process that uses considerably fewer resources than traditional dye processes. FC0 DWR (Durable Water Repellent) finish repels moisture. Lightweight, downproof 20D Arato liner‘s bio-derived material reduces petroleum use. Insulated adjustable StormHood provides warmth and coverage without impacting peripheral vision. Two-way reverse coil centre-front zipper provides ventilation and freedom of movement. Thigh length with side slits extends coverage without impacting mobility. Zippered hand pockets and internal dump pockets provide ample storage. Stuff sack included for compact transport.
