This is the PARAHEM W-MOTION HOODED JACKET from Descente's ALLTERRAIN line. It's an ultra-lightweight pullover shell jacket made with waterproof and water-repellent material. The hood incorporates Descente's unique Air Inflator (a function that adjusts the fit of the hood with air pressure). The size is the popular O size. Also, the zipper area is slightly torn, so it's being offered at a bargain price (see image 5). As this is a nylon jacket, it will be very useful in the coming season. First come, first served. Thank you.
