None that I know of, this item was made with the paintball player in mind.
I'm completely happy with this purchase, most of my field gear is made by DYE, this company keeps quality in mind when producing their products. I have tried many brands in my two years of playing this soprt and I'm very big on quality when spending hard earned money, you don't want to waste your money right? Then I suggest you go out and get this bag if you are currently looking for one. Read the spec on the item and compare them to others and you will see why. Peace!
This item is a must have if you have a lot of gear to haul, the handle and wheels makes it simple to move around and travel with.
