Our comfortable soft fabric Armbands combine an adjustable velcro closure with an elastic panel. Can hold a small mp3 player. The tension of the elastic keeps the Armband in place and the velcro allows the wearer to alter the band to the desired size. Armbands are 18" long and features our exclusive hidden pocket which can hold keys, money and ID. There is a large imprint area on the reflective portion for custom logo or message. Use for event staff at every race. These are also ideal for runners-in training and for promoting races, fitness centers, health clubs hospitals and other organizations.
