Review on MOLLE Hydration System MultiCam 8465 01 580 1316 by Josh Elkins

It's cheap compared to other options. The construction turned out to be solid (I abused that at Fort Benning, believe me). It's versatile in the sense that it has backpack-like straps and D-rings in case you want to attach it to your MOLLE gear. It's also easier to fill than some other models. It also comes with a mini pen clip so you can clip it to the front of your shirt, backpack or whatever to keep your hydration tube from dangling.
