The Endura MT500 Polartec Jacket uses advanced fabrics and technology to keep you comfortable on those dry but cold weather rides. The MT500 Polartec Jacket uses legendary Polartec Fleece to maintain warmth without getting bogged down during hard efforts while stretch-woven panels shield from cold wind and trail spray. A dropped rear hem adds coverage in a riding position while a snug-fit hood can be worn underneath a helmet for added insulation during the coldest rides.
