I was having difficulty finding a bag for my worm drive saw that was large enough and the 20 inch bag was perfect. I also had a cordless drill and some accessories that needed a home and a 16 inch bag proved to be the perfect solution .
Nicely structured and tough. They have a box shape when unzipped making it easy to put tools in and out. I keep my most used tools in the bigger one with a chalk line, drill bits, etc in the outside pockets. I use the small one for snacks and such when we go to the drive-in theater.
