Hand-picked favorites from our sponsored team of professional athletes.
Remixed for 2014 to deliver dialed warmth during active endeavors, our new insulated vest has lightweight ThermoBall™, powered by PrimaLoft™ synthetic clusters around the torso and back to protect your core in wet, cold conditions. The lightly insulated (60 g) upper chest and collar provide a sleek buffer against cool conditions.
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.
