The Sprint Tri Sleeveless is made of race-proven, renowned Endurexx fabric that dries fast and manages moisture efficiently. Mesh fabric in the back ensures efficient heat management on those hot summer days. When it comes to nutrition, new angled back pockets offer plenty of storage for bars and gels while preventing any loss during the race thanks to a tight elastic opening. A silicone gripper circles the bottom of the Sprint Tri Sleeveless to make sure it doesn't move up during effort. The reflective trims and logo make it a great asset for both early birds and nights owls.
