The DMK Sleeve increases the longevity of the DMK Fitbands. The Sleeve is made from strong nylon, heavy duty stitching and padded neoprene which acts as a barrier to protect and maintain the quality of your DMK Fitbands from any damage due to friction with rough surfaces. The sleeve can also be used to wrap around any objects or to sit/stand/kneel on when exercising. The Sleeve is light weight, convenient and easy to use. All you have to do is open the sleeve using the Velcro seal, lay your Fitbands in the center, seal the Velcro back up and you’re good to go!
