Yes, you're right, M_Albert about the orange color and the almost frustrating reviews sometimes. Sorry Medusa, I missed your post. By the way, the ROP is 20 l./1180 cu. in., the Typhoon is 13 l./750 cu. in. If the capacity and what you can put in depends how you fill/load your bag, the 400 cu. in. difference could be noticeable. I'm amazed what I can put in this "little" ROP everytime I need to fill it. I sometimes have to make three attempts, put things differently (like Tetris) to get it right but it fits everytime. As I told in my review, the choice made by Tactical Taylor not to divide the free room, maybe.
