Sharing the same great performance features you have come to expect from GORE-TEX®fabrics (waterproof, breathable and windproof), the outer layer has the added value of extremely low audible detection due to the brushed polyester (soft, fleece feel) face fabric which is treated with DWR (Durable Water Resistant) finish.
