The Reload Battery 2 - Battery Pouch from Tenba fits two DSLR batteries of varying sizes thanks to its stretchable neoprene pocket. The top flap of the pouch is made from water-repellent ripstop nylon and secures with a touch fastener. A touch fastener loop on the back side enables the pouch to be attached to your belt or shoulder or backpack strap. It also provides D-rings on back to attach a security cable or lanyard.
