STBG's Race Flag Tri Top is made of race-proven fabric that dries fast and manages moisture efficiently. Mesh fabric in the back and on the side panels ensures efficient heat management on hot summer days. When it comes to nutrition, 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 to make sure it doesn't move up during effort. Reflective trims and logos make it a great asset for both early birds and night owls.
