This is the belt version of the New Myo XP. It features the same head unit as the standard Myo XP but with a belt mounted battery pack to reduce the on head weight. The battery lead has a quick disconnect to make threading the lead easier and the battery pack can be replaced with a rechargeable battery pack (sold seperately). Ideal for use in cold environments as you can keep your batteries warm and get better performance out of them. The Myo XP Belt also features a permanent top strap rather than the optional one with the standard Myo XP.
