DetailsLouis Garneau Men's Standard Fit Size Chart The Sprint Tri Jersey is made of race-proven, renowned Endurexx fabric that dries fast and managed moisture efficiently. It covers the entire biceps with a silicone gripper that holds everything in place near the elbow. Mesh strips around the arms and at the back ensure efficient heat management and provide great amplitude of movement during the swim, bike and run. 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. The reflective trims and logo make for a great jersey for both early birds and nights owls.
