These arm bands contain many great features including: a comfortable inner lining; outer pocket for Ipod/phone/keys, and best of all embedded bio-ceramic material. The Bio Ceramic material in Delfin Spa's arm bands reflects your body's FAR infrared rays, the technical term for body heat. Increased heat combined with compression stimulates molecular activity, enhances the effectiveness of exercise, increases blood flow, and accelerates metabolism to burn more calories.
Our Bio Ceramic arm bands are COMPLETELY ADJUSTABLE as the entire outer side is lined with with the velcro 'loop' which is what the velco sticks to.
