For the money, the bag is a great buy. What I found is that the vinyl goes limp in the hot sun and looses its shape. I added some hard plastic on the inside, riviting it to the back and front sides of the bag. Problem solved.
All of my quality travel tools are kept in a slotted cordura tool bag; then covered with two heavy zip lock bags. The whole package goes into the Saddleman bag, which is mounted with velcro on the back of my luggage rack, and is additionally secured to the rack with a nylon strap. Overkill? Maybe; but It never lets go and the tools stay dry. The vinyl is good quality, the stitching is well done, the inner fold-over side flaps add extra security.
