The Portwest PW358 PW3 Insulated Work Trousers are made for cold days on the job. They pair a hard-wearing polycotton shell with a padded, lined interior, so you stay warm while keeping the pocket layout of a standard work trouser.
Top-loading knee pad pockets, a hammer loop and dedicated rule and spanner storage keep tools within reach. A gripper waistband helps keep upper layers tucked in. Reflective piping adds visibility in low light.
