This is a Gore-Tex waterproof and cold-weather set. It is made of anti-static material. Both the jacket and pants are size M. It comes with a full set of inner layers, making it a solid product. The inner layers appear to be removable (both top and bottom). It is new. The photos from the 6th image are of a new rain suit set, which will be included as a bonus. Please feel free to ask any questions!
