XP 2.5-layer fabricOur hard working 2.5-layer fabric offers a great combination of durability, waterproofness, breathability and light weight. 1) Nylon woven face fabric treated with a DWR (Durable Water Repellent) to prevent the fabric from becoming waterlogged so that it stays breathable.2) A hydrophobic, microporous polyurethane coating is applied to the face fabric. The pores are too small to allow water droplets to pass through, but large enough for water vapour to pass.2.5) On the inside a smooth textured diamond matrix print protects the microporous coating from abrasion and improves moisture dispersal. Waterproofness: 10,000 mm. Breathability: 4,000 g/m2/24hrs. Breathability tested by the A1 method.
