Helly Hansen Men's Dubliner Jacket Waterproof, Windproof, Breathable Shell Rain Coat with Packable Hood

HELLY TECH is the waterproof and breathable outer layer between you and the elements. Its unique membrane will keep water molecules out while allowing sweat vapor to pass through - keeping you dry from the outside and comfortable on the inside. It's a combination of a DWR-treated outer fabric and highly waterproof membrane, along with often an inner fabric, mesh, or lining. Pants are slimmer through the thigh and knee and won't go much below the ankle when standing up straight.
