Engineered for thermal warmth and superb moisture transfer, the Apache AR is a light insulating layer that's Great alone on sunny days or layered beneath a H2Oproof and breathable shell when the skies let loose. It's made with a velour-like Polartec Thermal Pro tweed fabric for comfort and moisture management. The gusseted underarm sleeves make this a superb choice for skiing, snowboarding or hiking in cool weather conditions. Weight-saving laminated elbow patches help minimize wear from abrasion on the elbows, but you may want to layer the Apache beneath a shell if you plan on taking extended backpacking trips. Stick energy bars or your car keys in the laminated chest pocket and you're Great to go.
