A functional shirt that is not skin-tight on the body? Yes, SQlab can, with the Jersey One Ox, the ergonomics specialist is launching a loose-fitting shirt for mountain bikers. The jersey is made from lightweight, breathable mesh fabric and is designed to keep you cool even on hot days thanks to the laser-cut ventilation holes. The V-shape in combination with the flexible stretch ensures a good fit with and without protectors. The welded seams on the cuffs and hem provide additional comfort.
