No matter what the mountain report calls for, bring this perfectly paired zip-in system to the hill for reliable weather protection and unmatched versatility. The durable, waterproof exterior shell has a subtle pinstripe, is finished with alpine-specific features and has longer 31-inch parka length for extra coverage. The PrimaLoft® ThermoBall™ liner jacket is removable, and can be worn as a standalone jacket around the base village and in the lodge.
A waterproof, breathable technology utilizing a polyurethane (PU) coating that consists of a tri-component, multi-layer formula for waterproof protection, moisture permeability and durability. HyVent® technology has been lab- and field-tested to ensure the best possible durability and function while also maintaining an optimum level of breathability. To test the level of waterproofness, we subjected HyVent® garments to 20 wash cycles, where garments retained an average of more than 60 PSI on the waterproofing Mullens test.
Developed in partnership with Primaoft, Inc., ThermoBall is a revolution in insulation technology. Unlike traditional continuous-filament synthetic insulation, the small, round PrimaLoft synthetic-fiber clusters closely mimic down clusters, trapping heat within small air pockets to retain warmth. Independent clo testing by Kansas State University has shown that ThermoBall has warmth equivalent to 600 fill goose down. As a result, ThermoBall can offer the lightweight warmth and compressibility of down with the wet-weather insulating performance of synthetic insulation.
