Factory Fit and Function Balancing art & speed with premium performance, the limited-edition A1 Collection’s vibrant, pulsating colors are painted across an SE Composite Helmet, SE Ultra Jersey and Pants, and Air Glove. Youth can relish in the excitement too with the Youth GP Pro kit. SE Ultra jerseys offer TLD's precision fit and is with laser-perforated ventilation for increased cooling airflow. There are mesh underarm panels to further support venting and evaporation of moisture. A drop-tail hem provides increased rear coverage, and the jersey uses welded seams. The SE Ultra jersey's 4-way TLD Ultra Mesh stretch fabric allows unrestricted movement. We added precision laser-cut ventilation and lightweight moisture-wicking material that makes for a high-end jersey that is built for speed and superior comfort.
