Looming clouds and certain precipitation are no match for the Mavic Men's Ksyrium Pro H2O Jacket. Made from lightweight, surprisingly breathable, and waterproof 37. 5 Xcelerator fabric, this jacket avoids the clammy conditions that plague so many others to keep you dry and comfortable through the deluge. Fully sealed seams prevent even the most persistent raindrops from making their way through, and Clima Vent boosts ventilation power by whisking sweat out and away.A streamlined fit keeps this jacket from feeling like a sail, and a zippered chest pocket keeps small valuables protected and close at hand. As an added touch a color contrasting, asymmetrical zipper for extra ventilation when the rain tapers off and a pop of style no matter the weather.
