What Our Gearhead® Experts Are Saying:"Bonatti Pro WP is the shell I grab when weight truly matters. It disappears in my running vest until the weather turns, and the Pertex Shield+ keeps me dry without that trash-bag feeling. The fit is athletic but surprisingly workable with a light midlayer, and the hood turns with my head better than most true minimalist jackets."We reach for the Salomon Bonatti Pro WP Jacket when the forecast looks questionable but we still want to move fast. Salomon built this featherweight shell around sleek efficiency, and it shows—from the streamlined profile to the subtle stretch that keeps us running, scrambling, or fast-packing without restriction. Despite its barely-there feel, the Bonatti Pro WP delivers authentic weather protection. The Pertex Shield+ construction blocks wind and rain, the seams are fully sealed, and the smart hood stays in place when conditions shift. A single chest pocket carries essentials and doubles as a packable pouch, making it easy to bring along on any mission, even when we hope we won’t need it.
