I got this pack for my Birthday. I had a small problem though, I had also got a remote for my Co2. My bros 14 oz brass eagle tank fit right in but to get my 20 oz Pure energy in I would have to stretch the holder to where it couldn't hold loaders anymore. First I wanted to try an alternitive. I bought a teeth clamp strap from army-navy store and strapped it to the loop on the top. The problem with that was that my Co2 wouldn't stopbouncing up and down and once it eventually fell out causing me to be shot out. After that game I decided I'd try ways to secure it but no matter what I did I couldn't get it to stay. So, I decided I'd sacrafice a loader instead.I could only get it into the second to the top one and it took alot of sqeezing but I finally got itand now everything works great its very lightweight, out of the way, Blends in, holds enough paint. I'm happy with it and now I wouldn't trade it for another harness in the world.
Conclusion:
Buy it, However it holds 14 oz or of equal size tanks best 20 oz will take some muscle (after the first time you get it in it will strech and you won't need to put in as much effort).
