Review on OP/TECH USA Battery Holster: Compact SLR Battery and AA Batteries Case by Yaisa Luster

I liked this bag. You can fit two Canon NB-10L batteries in if needed, but it stretches a lot, I think with some sun and heat the material will stretch and no longer hold batteries. slides down. I really liked that it rests over the shoulder of the pillow, it's out of the way and it doesn't restrict my movements. I took some shots with one battery and two batteries so you can see, in my case I only need to keep one battery in a small bag. In the first picture a battery inside and outside, in the second picture two batteries inside (on the side). I know it's short but it's right, I hope it helps you.
