The Reload Battery 2 Pouch carries two mirrorless or DSLR camera batteries. It has a rear hook and loop flap that attaches to a belt, shoulder strap, backpack harness or other MOLLE-compatible loops so you can keep batteries close at hand. The neoprene pocket stretches to accomodate popular battery sizes. Use the D-rings on the back to attach an optional security cable or a lanyard to hang batteries inside a jacket to keep them warm in cold weather.
