A rain jacket with everything you need.. This new Alpine jacket made of our Dynashell 2.5L fabric is superlight, breathable and totally waterproof thanks to taped seams. Our innovative Zip-Over Backpack System is now also integrated into this jacket. That means even when it rains hard, your pack and its contents are protected from moisture. The durable and still soft outer material enables you to also wear a pack on top of the jacket. The fabric has a very soft handfeel, is thin and has a small degree of stretch for more comfort during activity. For additional breathability, there are laser perforations under the arms. Reflectivity ensures visibility in poor weather. When the jacket is not needed, it can be quickly packed small and stowed in its own hood.
