For: Condor Outdoor Hydration Backpack (BLACK)This thing is awesome!
For $28 with a camel back it's even better, the two pouches are nice; one is quite large like on any backpack and the front pouch is a smaller one that has two small pockets in it, maybe a good place for cleaning supplies or batteries.
This is exactly what I wanted and looks like it will hold up for quite a while, it is well padded and fairly well insulated for the bladder.
The only problem I have with it is the zippers, they can be kind of a pain and come apart after the zipper passes over them, its easily fixed but they could be better quality.
All in all this is a very compact backpack, it will hold quite a bit of ammo if you need it for that. I was thinking of keeping another backup AEG in it such as a MP5K or MP7.
This would be a 5/5 if it wasn't for the zippers.
+Comes with the $14 Bladder which has an insulated mouth piece and hose
+Very comfortable, padded straps and back
+Strong connecting points for the straps and fully adjustable chest and waist snaps
+2 pouches and 2 pockets
+MOLLE webbing on the small pouch for connecting more pouches
-Crappy zippers, which is a fairly big deal on a backpack
