First off, I did not expect much from this bag. And just like some of the others who wrote reviews, I was glad to be proven wrong. The backpack is highquality and comes with a durable good quality 2.5 liter bladder. It works like a charm and even the first time you can't taste the plastic residue that my friend's Camelback brand bladder does. The large pockets can fit tons of things like mine fit a 5000 bag of BBs, pistol, 2 mid cap g36 mags and a drum mag. The smaller pocket can easily fit your wallet and phone anlong with pistol mags and pocket tools (allen keys, multi-tool, etc.) Great price and great bag.
two buckles so it doesnt wobble at all when your running
2nd lower buckle on mine is really tight and I'm not a big guy. The first buckle alone keeps it tight though so the second isn't a big deal
Plastic zippers (The plastic is tough, but metal is smoother and I trust it more)
Nozzle for the bladder is massive, folding it in the bag a bit doesn't cut the flow of water and adjusts it to your comfort
