I also have the Force3 but I think it is a slightly smaller version of the ultimate. It has an upper and lower compartment -- I put clothes in the upper and shoes in the lower. I take 2 pair of shoes to every game along with a pair of shower shoes. Everything I want to carry fits, but it is very tight. I sometimes have to get creative after the game as I put dirty and wet stuff in one of three bags and then arrange them inside the top part. In a pinch, I could put one of the smaller bags in the bottom compartment.
The bag fits longways (wheels off the leather) in my car backseat, and I have the seat back quite a ways. In an SUV or a trunk, its an easy fit.
