1xl, 1L, 1M Material: The jacket is constructed from 100% textured nylon with a Teflon surface treatment that helps prevent snow from sticking. It features a proprietary Nortex membrane system, a waterproof and windproof laminate designed to be highly breathable. Waterproofing: The Nortex membrane offers a high level of hydrostatic water pressure resistance, up to 16,000 mm, ensuring excellent waterproof performance. Breathability: A key feature of the Nortex fabric is that its breathing process begins at a lower relative humidity (40%), which helps prevent the wearer from sweating during high activity. Design & Features: The jacket includes fully welded seams, YKK waterproof zippers, mesh-lined underarm vents, and multiple functional pockets, including a left sleeve pocket with a lens wiper. It is typically a shell jacket, sometimes sold as a 2-piece with an inner insulated liner. Comfort & Fit: It is designed with action-shaped sleeves and adjustable cuffs, with soft inner cuffs to prevent snow entry.
