We worked closely with mountain pros to develop this backcountry-specific jacket, designed for high-output activities in challenging conditions. The Lifa Infinity Pro™ 3-layer fabric provides exceptional and durable waterproof/breathable performance without intentionally added Pfas. The jacket does not need reproofing. It remains hard-wearing and high-performing, no matter what nature throws at you. Backcountry-specific features like helmet, backpack-compatible construction, ventilation zippers, roomy gear pockets, as well as a Recco® transponder, make this jacket the ideal companion when ski touring in deep powder.
