Protect yourself from passing storms with a lightweight jacket that's totally waterproof and packs down easily into a jersey pocket. Most rainjackets are bulky. They might protect you from the weather, but when the sun comes back out then you’re stuck carrying them. The Cosmic H20 Jacket is different. It offers waterproof protection and still packs down easily into a jersey pocket. Designed for gran fondo and sportive racing and training, this is a jacket that you can always carry when riding in alpine environments, where the weather can turn quickly, or in changing seasons like fall and spring. It weighs just 110 grams (size medium) and fits easily into a jersey pocket when packed down. Even with its superlight construction, the Cosmic H20 Jacket still offers total waterproof protection. Its 2.5 layer fabric features a durable woven outer shell with a polyurethane membrane that blocks out rain and road spray. We made this jacket with a close-to-the-body “Pro 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 the extended tail shields you from rear tire spray. Lastly, we added integrated reflective print for improved visibility in low-light conditions. No reason to let stormy weather stop you from riding. Now you’re ready for anything. Portable protection from rain and storms. Weighs only 110g (M size) and it folds into half a jersey pocket. Stay dry and comfortable in wet, stormy weather. The 2.5 layer fabric features a durable woven outer shell with a waterproof polyurethane membrane rated at 10K WP (5K MVTR). "Pro Fit" so you slice through wind faster. Body-hugging fit prevents fabric from flapping in the wind.
