Answer 4's 100-mile black T-shirt. This original body T-shirt uses Toray's "Primeflex®", which features quick-drying, stretch, and UV protection. - Tapered hem to prevent riding up while running. - Slightly tighter silhouette, designed to be worn with a jacket. - Seams moved forward to prevent weight from being placed on the seams when wearing a backpack. I purchased this before, but I haven't used it much, so I'm selling it. The width is 49cm and the length is 71cm. It fits perfectly on a man who is 175cm tall and weighs 65kg. Thank you for looking.
