Gamer GO Module Designed for the mobile gamer in mind who needs to keep their hands free, this arm pocket is made to hold up to the largest mobile phones on the market, along with a spare battery charger. The front edge is open to allow you to extract the phone in case a call comes through. A passage for a USB cord is provided between the phone and the spare battery. In addition, a thin vinyl screen cover helps protect your device against incidental moisture and debris. The adjustable arm straps are made to fit up to a 7 to 8-inch wrist, and up to a 14-inch forearm. As always, please notify Dr. Sabins directly if you need one of these made in a more custom size. These handy accessories are worth $35 USD, plus shipping.
