This Sealtex AIR waterproof jacket is built for outdoor work in wet weather. Welded seams keep rain out at the joins. The breathable fabric draws moisture away from the body, so you stay drier from the inside during active work.
The 4-way stretch fabric moves with you when you bend, reach and climb. A durable, wipe clean surface makes it easy to keep clean between wears. A drawcord hood, double storm flap and adjustable cuffs help seal out wind and rain.
