The RunWallet is a soft, neoprene arm wallet that can accommodate the above items in a secure Velcro closure. Each RunWallet consists of a flexible armband strap that can accommodate both large and small arms.
As a fitness wallet, the RunWallet can be attached to the supplied armband, or can be attached to your shoe, attached to a belt or placed in a pocket.
