Specialized Trail-Series Alpha Jacket
Our Trail-Series Alpha Jacket utilizes Polartec® Alpha® to bring warmth to your cold-weather days. The soft, inside liner quickly evaporates sweat keeping you warm and dry. With a casual style, it's 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 and heat to expel from your body.
- Exterior shell fabric is engineered to breathe even better and move moisture from the insulation to the exterior to dry—keeping you dryer than ever before.
- Relaxed Fit Trail Jacket is loose and comfortable, and also provides plenty of room for layering underneath.
- Fabric Content: SHELL: 85% Nylon, 15% Spandex; LINING: 100% Polyester.
Occasionally, without notice, manufacturers change product design and/or specifications.
