Take on the cold with this ThermoBall™ hybrid training jacket that offers all-weather versatility. A fully lined hood provides added warmth.
WindWall® fabric is a wind-resistant fleece. WindWall® utilizes a unique fabric-bonding process that allows a limited degree of external air permeability (approximately 20 CFM), which drastically reduces the effects of windchill and enhances your warmth and comfort. WindWall® 1 fabric has a mesh liner, while WindWall® 2 fabric has a grid fleece liner for even greater insulation.
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.
