The Portwest DX465 DX4 3-in-1 Jacket gives you year-round weather protection in one system. A waterproof, windproof and breathable stretch outer jacket pairs with a detachable insulated baffle jacket, so you can adjust your warmth as conditions change.
An ergonomic cut and raglan sleeves give you a good range of motion for active work. The longer back length, wind cuffs and adjustable hood add extra protection against wind and rain.
