Slip on a pair of Pearl Izumi Thermal arm warmers and experience the mobility and warmth that only genuine Elite Thermal Fleece fabric can provide. The fabric's nylon face sheds the weather while a brushed polyester back is soft next to your skin. Ergonomic paneling provides an optimized, cycling-specific fit and eliminates bunching through your full range of motion. Silicone grippers hold warmers in place. Reflective logos enhance visibility.
