A third party brand USMC Woodland Marpat (w/100oz hydration bladder) backpack.  Lots of compartments.  Hip belt built in because this thing is pretty big.  Close to a 21" by 15" in size, variable depth with the compartments and compression straps on the side.

I don't use this like ever.  Refer to pictures for condition.
