Using these reflective straps is a breeze. Just wrap the elastic web around the part of your body you want, like your arm or leg, and secure it with the Velcro closure. You can wear them for running, jogging, cycling, or walking at night or in low - light. When using, make sure the reflective center is facing outwards for maximum visibility. For maintenance, hand - wash the straps in cool water with mild soap and let them air dry. Avoid using harsh chemicals or machine - drying, as this could damage the reflective material and the elastic. Store them in a cool, dry place when not in use.
