Our Trail Alpha Jacket utilizes Polartec Alpha to bring warmth to your cold-weather days. The soft inside liner quickly evaporates sweat keeping you warm & dry. With a casual style its right at home on the trail or enjoying a post-ride beverage around the fire pit. Polartec Alpha Direct Insulation increases breathable performance in this super lightweight mid-layer. Alpha technology eliminates the need for a backing fabric which allows the fabric to be in direct contact with your skin. Lofted fibers keep you extremely warm while allowing sweat & heat to expel from your body. Exterior shell fabric is engineered to breathe even better & move moisture from the insulation to the exterior to dry—keeping you dryer than ever before. Relaxed Fit Trail Jacket is loose & comfortable & also provides plenty of room for layering underneath.
