Zivalo 3M Scotchlite Reflective Arm Bands (Pair) for Running, Cycling, Walking and Hiking - Elastic, Lightweight, Adjustable and High Visibility of up to 1000 feet BE SEEN AND SAFE - Zivalo's reflective material incorporates 3M Scotchlite's patented retro reflection technology and offers higher visibility than other reflective films. Our reflective Arm Bands provide highest visibility for running, cycling, walking and hiking during all weather conditions, day or night. 360 full body coverage ensures visibility in all viewing directions. HIGHLY REFLECTIVE - Our reflective film uses spheres to collect light and bounces it back to the source, and the source only. When a car's headlights illuminate our reflective Arm Bands, the 3M reflective film "lights up" and sends the reflection right back to the driver. LIGHTWEIGHT MATERIAL - Zivalo's Arm Bands consist of a high quality neon green fabric material with velcro and 3M Scotchlite reflective tape. You will never have to worry about batteries again, like with an LED product. The bands are 10" long and 1.6" wide. They can be stretched up to 15" and can be worn as ankle bands as well. The silver 3M reflective strip in the center is 0.8" wide. COMFORTABLE AND LONG LASTING - Our lightweight Arm Bands allow a comfortable fit over sports gear and clothing. They stay in place and won't move around. The bands are easily adjustable, fit most adults and can be worn as Ankle Bands as well. Built to last with durable materials and strong stitching: Even under harsh conditions, our products will not let you down. HASSLE-FREE MONEY-BACK GUARANTEE - If for any reason you are not 100% satisfied, within 30 days, please return your reflective Arm Bands for a no-questions asked, full refund.
