Our ultra-versatile RainPac Trench Coat is a durable, waterproof shell that packs into a pocket to become a functional backpack when the skies are clear. The 2.5-layer WeatherEdge® waterproofing keeps you dry while the moisture-shedding finish prevents water from soaking into the fabric. Secure pockets keep your essentials safe, and the adjustable hood and hem seal the weather out.
