Named after the challenging route up Denali that was first identified by legendary photographer Bradley Washburn, the new West Rib Parka takes its place at the summit of Marmot’s technical insulation collection. The insulated jacket uses a new baffling construction designed to trap the maximum amount of air against your body to help keep you warm.
Called WarmCube, the construction technology employs unique 3D baffles on the inside of the jacket to multiply the insulating power of the 800-fill power goose down by conforming to the shape of your body and trapping warm air next to your skin. Combined with an additional shingled layer of 40 grams of synthetic insulation, the West Rib Parka makes the perfect alpine climbing warmth layer for belays or a last minute bivy.
The outer shell of the West Rib is made from Pertex Quantum ripstop nylon ensuring that the jacket is lightweight at just 2 pounds 5.9 ounces. The insulated jacket features dual zippered chest pockets and zippered hand warmer pockets. Inside the belay parka you’ll find two mesh stash pockets for stowing an extra pair of gloves, sunglasses, or other gear.
The Marmot West Rib Parka will come in five sizes — S, M, L, XL, and XXL — and retail for $600. Expect the belay parka to start shipping in August.
