If you begin your approach and feel it start to drizzle, zip up the Men's Keele Peak Jacket, a fast and light shell that's designed for speedy ascents. 3-layer Pertex Shield® fabric is windproof and waterproof, yet offers breathability and 2-way stretch. 100% seam taping prevents water from sneaking in. Its 2-way, water-resistant center front zipper prevents bunching. Core vents mean you can add this shell to your climbing pack for comfort all year long. Articulated elbows make it easy to move when layered. The attached hood offers maximum coverage with an adjustable drawcord at the back that won't interfere with a helmet.
