Finally, you can leave that stiff, bulky rain shell on the coat rack where it belongs. The Cosmic H2O Jacket blends bomber protection from precip with two layers of supple stretch fabric for maximum maneuverability and comfort.

Its slim profile helps riders cut through the wind versus getting blown about like a sailboat in stormy seas. Plus it captures and retains the body heat generated while you’re cycling through the ups and downs of challenging weather and terrain.

Often, light weight can mean sacrificing waterproofing and durability, but the Cosmic H2O Jacket defies the odds by layering a durable knit outer shell with an 8K waterproof polyurethane membrane. Its 2 layer fabric features a durable woven outer shell, and the polyurethane membrane blocks out rain and road spray. All these features add up to a sleek package and pocket-size protection, and the jacket weighs in at just 110 grams.

Designed for gran fondo and sport racing and training, the Cosmic H2O Jacket is a must-have when riding in alpine environments and remote locations, where the weather can turn inhospitable rather quickly, or in changing seasons like fall and spring. Protection is paramount, and the Cosmic H2O Jacket prides it in spades.
