Constantly changing weather is part of cycling, and the Men's Endura Photon Jacket has been designed for those swift moving mountain or valley rain storms that can blow in on a moment's notice. Ultra compact, the Photon easily fits in a jersey pocket. But its light weight doesn't mean the Photon compromised weather protection. In fact, the Photon's 2.5-layer laminated fabric is waterproof, thanks to a membrane in the fabric. This not only blocks rain--the membrane is permeable and will allow your perspiration to pass through. The result is a dry core which means you'll be warmer and more comfortable, both riding and sipping coffee afterward. Wide, elastic cuffs offer a windproof seal between gloves and the jacket. An inner storm flap with wrap over zip guard won't let nasty head winds seep in, either. The Endura Photon Men's Jacket has one large rear pocket for storage, and it comes with a stuff sack. It comes in Black, Yellow, or Red, and sizes Small through XX-Large.
