Stay dry and comfortable in heavy rain.

3-layered stretch fabric with 37.5® technology is 20,000mm waterproof and has fully sealed seams.

Don’t overheat, even during intense efforts.

37.5® technology uses active particles to draw heat and humidity away from the body for faster evaporation, better breathability and increased comfort.

Wicks moisture 5 times faster than a standard membrane.

"Pro Fit" so you slice through wind faster.

Close fit construction prevents fabric from flapping in the wind.

Waterproof membrane offers high mechanical stretch.
You can’t control the weather. But you can control your own comfort—even in the heaviest rain, pushing your heaviest pace. The Cosmic H20 SL Jacket is your own personal climate control system, sheltering you from the elements while allowing body heat to vent out. The secret is 37.5 technology, a highly waterproof material that’s also very breathable. It uses active particles to capture and release moisture. These particles respond to body heat, using it to accelerate vapor movement and convert liquid to vapor. So, the hotter you get, the stronger the driving forces that push out moisture. That means you can ride harder, even at slower speeds or on steep climbs, without overheating and sweating. Based on feedback from pro riders, we also made this jacket superlight and stretchy, with a close fit that doesn’t flap in the wind. The sleeve shape is optimized for an aggressive riding position, and an ergonomically designed cuff fits snugly on the wrist. All the seams are fully sealed, and a new extended tail shields you from tire spray. Lastly, we added integrated reflective panels for improved visibility in low-light conditions. With a jacket this good, you might pray for rain.
