You can exert yourself longer without having to take off the jacket. It is equipped with FUTURELIGHT™, a customizable, breathable, waterproof material. The fabric is produced using nanospinning technology to create breathability while ensuring waterproofness. Additionally, it is made from recycled polyester and treated with a durable, PFC-free water-repellent finish, giving it excellent sustainable properties. The jacket is the ideal three-layer outer layer for comfortable mountain hikes and hut-to-hut treks in changeable weather – you don't need to constantly put it on and take it off. The stretch-knit underside does not feel cool against bare skin, unlike other materials. If you use your phone for photography or as a GPS, the secure phone pocket proves to be extremely practical. No water can penetrate, even if you leave the pocket open.
