50D T800 + PU Membrane 3-in-1 Fabric

Superior waterproofing and hydrostatic pressure resistance（20,000mm H₂O）   Fully rain and snow proof: It withstands heavy rain and blizzards in extreme harsh weather, with no water penetration even after prolonged exposure to humid conditions.Cool-sensing fiber, Nylon fabric, Fabric   Excellent hydrostatic resistance: Rated at 20,000mm, the fabric resists leakage under the pressure of a 20-meter water column. It delivers reliable protection not only for daily rainproof use, but also in demanding scenarios — such as long-term compression from backpack straps during mountaineering, or pressure from melting accumulated snow after falls while skiing — keeping the inner layer completely dry at all times.   Long-lasting protection: Fabrics of this grade adopt high-quality waterproof coatings or functional membranes such as ePTFE. They feature outstanding durability, and their waterproof performance will not easily degrade due to abrasion, friction or repeated washing.
