I love my USMC Desert MARPAT backpack. It has ALOT of room. I especially like the fact that you can unzip the sides to give you even more space and the fact that it comes with a hydra pack to fill with water to drink. Wish I could upload a picture to show. Im a Marine veteran who was looking for a Tactical USMC backpack and I definitely found what I was looking for. I definitely recommend it!
