The lucky winner is Michelle Cheah and the answer is N80p-X GORE-TEX® Face fabric.
N80p-X GORE-TEX® Face fabric was developed over a five year period and is very abrasion resistant. The breathability in wet conditions is better using the DWR (durable water repellent) materials. Woven from an 80 denier false twist texture, high tenacity nylon yarn, the fabric is durably waterproof and breathable, while at the same time being supple, quiet and 10 percent lighter than the former version of the fabric.
