PrimaLoft® SPORT is a premium performance insulation engineered for superior warmth, water resistance, loft, softness and compressibility. PrimaLoft® SPORT insulation keeps the body warm, dry and comfortable, even in extreme conditions.
Fine fibers form tiny air pockets that trap body heat and keep the cold out. The result is immediate warmth without the bulk. Fine fibers are engineered for permanent water resistance and create tight surface tension that resists moisture penetration, resulting in an insulation that dries faster than goose down. Fine fibers mimic the compressibility of goose down and are breathable, allowing moisture vapor to be transported through the fibers and away from the skin.
