The next-generation Alpine Arm Warmer has been taken back to basics. Leveraging a high-stretch fabric, we simplified construction to a single seam for reduced chafe points without compromising fit. An all-new cuff design is made from fabric featuring Reflective Technology™, providing visibility from all angles. A large, reflective logo adds additional visibility in low-light conditions. We love the ThermaGuard fabric for its compressive fit and a soft feel against your skin. It's not overly warm while providing the perfect amount of protection for those days when you need to cut the cold without overheating. The gripper band is possibly the most critical component of any warmer, so that's why we searched high and low for the best combination of sturdiness, stretch, soft touch, and grip. We think we've found the perfect answer with the wide, stretchy, and soft grippers in these arm warmers. While they hold incredibly well on their own, we went ahead and added a tenacious silicone print to the interior (skin side) to ensure the bands stay locked in place. We recommend washing the warmers prior to wearing them to activate the Silicone for the best grip. Warmers work best and stay in place when placed directly on the skin, not over a jersey or base layer as Silicone is not designed to grip fabric.
