I wish the carrying bag was made as strong as the car seat, but unfortunately, it's not. I've now gone through 2 of these, each one has only made for part of a trip and died. The first bag had the shoulder strap holder tear loose from the bag while in the security, the second bag had the seams bust apart in two locations and the zipper pulled off the track.For those interested I managed to salvage some portability of the unit by purchasing a luggage strap from target and using it to strap the folding seat closed. Then I used one of the shoulder straps from the case and fastened it to the the nylon eyelets one side of the chair.
