the bag be make of heavy rip-stop nylon that will probably outlast I . I do not use this professionally , but I always have a lot of project in my `` off '' hour . the bag have many nice pocket -lrb- though I do not find they very useful in practice -rrb- and a sturdy zipper . the big downside be that there be no stiff bottom in this bag , unlike every other bag I have use . tool all slump to a heap in the center . I 'll cut my own , but I should not have to . a minor complaint be that the handle be just a nylon strap . I much prefer the feel of the nylon strap on the ` ridgid ' brand bag which have a stiff cord in the strap . hard to describe , but it be a nice feel . Ridgid have a nice 22 '' and a nice 17 '' . if you like a small bag , Stanley have a nice 12 '' .
