The name says it all: the Chameleon Dual is a versatile technical garment designed to adapt for every kind of mountain athlete. Thanks to detachable sleeves, you get two products in one for the best comfort and performance independent of the specific activity or conditions. Ski mountaineers will zip off the sleeves for climbing and reattach them for the cold descent. Climbers will find special use for the detachable sleeves as they climb through sections of sun and shade, wind and shelter or switch from the sharp end to belay slave. The Chameleon Dual Jacket combines premium grade white duck down with PrimaLoft® synthetic fills in a way that maximizes each material’s specific attributes. Down is used on the front and back panels, shoulders, and outer sleeves to ensure the best thermal insulation for the core. PrimaLoft® is used on the side panels and inner sleeves. The durable and breathable Hitex (Nylon Ripstop) 15D shell features an improved DWR (Durable Water Repellent) treatment that is more resistant to washing so it maintains its excellent water repellency over time. A lightweight hidden hood, inner and outer pockets and a special Stow-Away Pocket (self-contained packing pockets standard on our Essential outerwear) round out the features on this incredibly high-end jacket … vest … which one is it?!
