TYR Arm Coolers give you the high-tech protection you need to stay focused on your race and not on your gear. Because 120 Miles on a bike isn’t just demanding on your legs, our Arm Coolers feature super cooling construction to keep you from overheating and a second-skin fit to rapidly wick moisture. Internal silicone grippers keep TYR Arm Sleeves right where you want them, while an ergonomic shape provides a full range of motion. Featuring SPF 50 protection and sewn-in mesh venting, the SLAC6 Arm Coolers combat the bitter headwinds, blistering sun and sustained vibration that take a toll on your upper extremities. Sold in pairs: Ideal for running and cycling. 80% Polyester / 20% Lycra® SPORT.
