The Universal Sport ID Bands are perfect for your active lifestyle. The cool part about this sport ID band is you can interchange your Contempo, Max Contempo or Wave ID tag onto this band from your chain, cable, leather, rubber, stretch,woven or beaded bracelets. This allows you to take your emergency information from your active day right into your evening attire by simply switching the ID from one bracelet to the next! Another plus to this sport band is that the metal does not touch your skin, which is nice for those allergic to metals! 3 sizes are available and they're adjustable with a Velcro closure.
