The R5 GTX Infinium Tights by Gore Wear are slim-fitting trousers that protect you from the cold and wind without restricting your freedom of movement. A three-layer windstopper laminate is used in cold-sensitive areas such as the knees and crotch. The trousers have a zip pocket on the leg and one on the back of the waistband, reflective elements all around and zippers on the leg cuffs.
