The Portwest S427 is a hi-vis traffic jacket built to adapt to changing weather through the working day. It can be worn seven ways, so one jacket can cover cold, wet and milder conditions. The outer shell is breathable, windproof and waterproof with taped seams, and the detachable inner jacket adds a padded layer when the temperature drops.
Reflective tape and piping add to your visibility. A radio loop, D-ring and ID card holder keep everyday kit to hand. Thirteen pockets give you plenty of storage, including a concealed phone pocket and an internal tablet pocket.
