XP 2-layer fabricOur 2-layer fabric is packable, lightweight, waterproof and breathable, which is ideally suited for our recreation and touring gear. Woven face fabric treated with a DWR (Durable Water Repellent) to prevent the fabric from becoming waterlogged so that it stays breathable. A hydrophobic, microporous polyurethane coating is applied on the inside. The pores are too small to allow water droplets to pass through, but large enough for water vapour to pass through to the outside air. Waterproofness: 5,000 mm. Breathability: 4,000 g/m2/24hrs. Breathability tested by the A1 method.
