The Hex Cable Keeper (Black) is an ideal companion for jogging and other athletic activities. The Cable Keeper routes your headphone cable through its built-in cable management tab to keep it out of the way while you work out. The Cable Keeper is made from comfortable neoprene and has an adjustable closure to fit a variety of arm sizes. It also has reflective tape for increased night-time visibility. You can use the Cable Keeper along with the Hex Watch Band (sold separately) for a terrific portable audio exercise solution.
