The Gore Bike Wear Visibility Thermo Arm Warmers may at first come off as excessively bright, but we contend that a little added visibility never hurt anyone. In fact, the opposite is true: these warmers are so effective at raising your public profile that drivers may well see burned in ghosts of your image long after passing you, but they'll pass you safely. The Visibility Warmers feature Thermo stretch fabric which has a soft, brushed lining, insulates your body, and wicks moisture and flatlock seam construction eliminates friction on your skin. The Visibility Warmers also have plenty of reflectivity to go with their retina burning intensity. Both forearms bear reflective designs, and there's a reflective Gore Bike Wear logo on the inside wrist. The Gore Bike Wear Visibility Thermo Arm Warmers are available in five sizes ranging from X Small to X Large in a very bright Neon Yellow.
