The wolfman is still sitting on my workbench so I don't have a good comparison but it is definitely larger than the d-b-g bag (I have the regular sized d-b-g, not the large). I was happy with the d-b-g bag but wanted to go larger and came upon a good deal on an almost new wolfman (I'm a fan of wolfman and have a number of their other bags)

I made a platform out of plastic cutting board to use as a base for the d-b-g bag and then attached the cutting board to the fender using the stock tool bag holes. It was pretty slick and worked well. I may have some pics if interested.
