A jacket doesn't have to be waterproof to keep you comfortable in occasional rain. If you can avoid a jacket with tape seams it will allow extra breathability to keep it from feeling like a sauna on the inside. With our 2L WxB Membrane technology, this jacket sheds all but the worst of the rain, which makes it perfect for anyone who wants a weatherproof jacket. The ultra-light fabric has superior stretch to provide a compressive fit like the rest of your professional kit. Two-way front zipper allows you to dump excess heat during a climb or access your rear jersey pockets. Thanks to its low gram weight and minimal bulk, it fits easily in a jersey pocket when the sun emerges, making it easy to stow for the unexpected.
