Built for riders who don't flinch at the sight of storm clouds, the Men's Summit PRO NeoShell® WxB Jacket delivers elite-level protection for all-day trail missions and bikepacking epics. This is our most advanced mountain bike shell—fully waterproof, highly breathable, and built to move with you when the ride gets rowdy. Crafted from Polartec® NeoShell® 3-layer ripstop fabric , it combines exceptional stretch with durable waterproof performance that's fully seam sealed to block out the elements. Unlike traditional rain shells, NeoShell® allows heat and moisture to escape, keeping you dry inside and out—especially on high-output climbs and long technical descents. A two-way YKK Aquaguard® front zipper offers customizable airflow, while the over-the-helmet hood provides full coverage without limiting your view or movement. Designed with a trail-specific fit , articulated sleeves , and a drop-tail hem , it delivers coverage and mobility where you need it most. And when the skies clear? The jacket packs down small to stash easily in a frame bag or pack. Pair it with our Summit AmFIB® Lite Pants for full foul-weather defense, or explore more men's mountain bike jackets built to thrive through all four seasons.
