By utilizing our BD.dry™ waterproof/breathable/windproof solution, the Treeline Rain Shell comes at a value and is engineered to shield you from mountain showers while cruising the trails. Featuring a 2.5-layer 10K/10K fabric that’s fully seam-sealed, the Treeline is breathable and moves with you while on the go but remains 100% windproof and waterproof. A YKK® Aquaguard center front zipper keeps moisture out, while the DWR adds ventilation. A back vent with mesh pockets also keeps you dry and cool with passive airflow. We’ve also included two backpack-friendly zip hand-pockets to store your on-trail essentials. The single-adjust climbing-helmet-compatible hood protects you in the heaviest downpours while the adjustable hem and cuffs dial in the fit on the move.
