Takes the edge off. Reduce the punishment of racing through scorching sunshine and oppressive temperatures with the TYR Competitor Arm Coolers. Shaped with an ergonomic design, the Competitor Arm Coolers tightly hug your arms without restricting key movements on your bike. Internal silicone grippers prevent them from sliding around throughout your race. Built-in mesh venting and quick-drying fabric actively cool your arms during triathlons and training scenarios alike. Plus, SPF 50 protects exposed skin from sunburn, especially when you're riding through exposed stretches and higher elevations.
