This isn't a backup layer—it's your go-to when the ride won't wait for the weather to pass. Built with fully waterproof and windproof Polartec® Power Shield® fabric, the Men's PRO Rain Jacket delivers unmatched breathability through a bio-based membrane that keeps heat and moisture from building up on the inside—no matter how hard you're pushing. The 4-way stretch construction moves with you, keeping the fit streamlined and responsive through tempo efforts and head-down descents. Details like stretch cuffs, a waterproof two-way YKK® AquaGuard® zipper, and a patterned silicone hem gripper lock out the elements while giving you mid-ride access to rear pockets. An internal zip pocket protects valuables, while PFAS-free PI Dry® technology adds sustainable water repellency. Premium 3M BioViz® reflectivity across all sides ensures you stay seen when visibility drops. Engineered for the breakaway. Proven in the storm.
