The Portwest S437 Winter Traffic Jacket is a padded, waterproof jacket for outdoor work in foul and cold weather. A tough 300D polyester Oxford shell with a double PU coating keeps rain out, while the padded lining holds in body heat.
A studded storm flap and inner ribbed cuffs help keep wind and rain out. The drawstring hood packs away when the weather clears. Several pockets, including a phone pocket and an internal pocket, give you room for everyday essentials.
