The Louis Garneau's Arm Warmer 2 is the perfect accessory when you don't know what weather to expect around the next bend. In Colorado, it can rain sideways one minute and be a sunny 80 degrees the next. Warm Heatmaxx fabric supplies top-tier insulation using a soft-brushed interior to retain heat. The biceps silicone grippers hold these warmers in place yet they're easily removed and stashed in a pocket or pack when things warm up. The arm warmers feature flatlock seams for less chafing, plus provides UPF/SPF 50 protection with reflective accents.
