Gamer GO Module Designed for the mobile gamer in mind who needs to keep their hands free, this arm pocket was made to hold up to the largest mobile phones on the market, along with a spare battery charger. The front edge remained 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 were made to fit up to a 7 to 8-inch wrist, and up to a 14-inch forearm. These items can be made for $35 each. As always, please notify Dr. Sabins directly using the Contact page if you need one of these made in a more custom size.
