Great stories, big days in the saddle and riding with friends. The TRAIL collection extends that range: forgotten roads, game trail single track, perfectly spaced berms and gnarled ascents figure larger into riding every day. For the Radiator Trail Tee, Velocio took the same Polartec Delta fabric found in their SL Radiator Base Layer and made a trail inspired tee out of it. Slim fit, longer sleeve length and added coverage at the back, this tee will keep you cool well into the mid-summer heat. Delta's unique composition, which includes Tencel, absorbs moisture which provides a cooling effect as it evaporates. Polyester yarn gives the fabric strength and stability. The mesh structure keeps air moving yet still remains opaque.
