Remixed for 2014 to deliver dialed warmth to your core during active endeavors, our lightweight ThermoBall™, powered by PrimaLoft™ jacket places synthetic clusters at the torso and back to protect your core in wet, cold conditions. The lightly insulated (60 g) sleeves and shoulders provide a sleek buffer against cool conditions without restricting arm turnover.
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.
Layer up in the backcountry with a long-sleeve shirt and waterproof pants designed for on-trail performance. The new, highly packable ThermoBall Remix jacket is a must-have for lightweight warmth in cold, wet conditions.Shop This Outfit
