The Oreus Hooded from MOUNTAIN EQUIPMENT is a synthetic insulated jacket designed for mountaineering, ski touring, climbing, and mountain hiking. Its Aetherm™ Precision Insulation , made from 100% recycled polyester, combines synthetic fibers with a heat-reflective layer to deliver warmth close to down, while remaining breathable, compressible, and less sensitive to moisture. Recycled PLASMA 10D fabric with a PFC-free water-repellent finish keeps the jacket very lightweight. Helmet-compatible insulated hood, articulated sleeves, three zippered pockets, and an interior pocket that doubles as a stuff sack: wear it as an outer layer, a warm midlayer, or a belay jacket.
