What Our Gearhead(R) Experts Are Saying: "This is the shell I grab when the forecast looks questionable but I still want to run fast. It's incredibly light, blocks wind well, and breathes better than most jackets in its class. I like how the slim fit doesn't flap around when the pace picks up, whether I'm on roads or trails." Bad weather doesn't get a vote when we're lacing up, and the Bonatti Waterproof Jacket is the reason why. Designed by Salomon for runners who head out no matter the forecast, this shell keeps us dry and protected while staying light enough to forget we're even wearing it. The AdvancedSkin Dry membrane uses a breathable microporous construction to block rain and wind without trapping heat, helping us stay comfortable through changing conditions. With a streamlined, slim fit and minimal bulk, the Bonatti moves naturally with our stride, making it a trusted layer for year-round road runs, trail miles, and fast efforts when the skies won't cooperate.
