I have tested this roll bag and another one, less expensive. This one is definitely better : larger, better finish, with a zip-closed pocket, a central elastic strap, and two straps with buckles to close it easily and firmly. BUT these two straps are way too short : with some "big" tools inside (pliers, standard screwdrivers...), it can't be closed. It would be perfect with 20 or 25cm more.
