Produced using Low Impact Technology (L.I.T.™) which uses less dyestuffs, thermal energy and water for enhanced softness, performance and after-care quality. This 7.1 oz. 100% polyester vest features a reverse coil zipper, chin guard, zippered chest pocket, front zippered pockets and stretch binding at armholes and hem.
