ONLY ONE AVAILABLE
 
This bad boy can hold about 75 liters of milk. That's a lot of milk.

These are great for any big hiking or camping trip you plan to go on. It features a hip belt to distribute the weight, quick-release shoulder straps, a top and bottom opening for ease of access, MOLLE straps to add even more items to the pack, two sustainment pouches, and a few internal pockets. 

There is also a plastic frame that has two small cracks (as seen in the photo provided), but it does not seem to affect the pack and can probably be repaired.
Other than that, the pack does not appear to have any fraying, holes, or stains.
