If demanding sports like trail running and cycling are your thing, an ultra-light and super-packable protective rain shell is a must. That’s why Salomon built the men’s Bonatti Pro Waterproof Jacket. This super minimalistic shell delivers 20K waterproofing and breathability, thanks to its thin yet durable 2.5-layer construction made with a combination of AdvancedSkin Dry and Pertex Shield technology. It also has ergonomic MotionFit construction so that it can withstand the strenuous movements of endurance activities. A waterproof Smart Hood stays close thanks to strategic elastic trim, while the single zippered chest pocket doubles as a stow sack for this entire jacket.
