any ideas where i can get a nice (cylindrical) fork bag for my Fat Bob?

I'm not that interested in the typical leather toolbag style.

A guy at my work has a black nylon nylon type material bag with plastic quick lock buckles on his Night Train.

I think it is about 8" in diameter and about 12" to 16" long.

A few separate storage areas too etc.

i love the bag, but he said he got it a bike show.

i can't find anything like it on the net or in the stores.

any help would be appreciated.

Thanks!
