The Fatboy looks MUCH bigger in the pictures than it really is. When mine arrived I was surprised to see how small it is. (it gets even smaller once you take our the packing paper). I think for the pics. maxpedition is again probably stuffing it with packing paper to make it seem larger. The Toadstool and the Thermite are smaller. I liked the Fatboy because it has an orientation which means it hugs the body better. If you are in doubt a lot of online stores have very reasonable return policies.
