After just a few short hours of use carrying liquids (water packs, herbicide sprayer; so less than 42 pounds) one of the shoulder straps separated near the bottom of the frame. Given other reviewers' comments, it seems that the other straps may also fail. So I'm going to have to learn how to sew webbing.Aside from questionable reliability, it's comfortable and light enough. My uses are relatively unconventional, but with a touch of creativity and some add-on straps and accessories, I think it will do the job. It's a shame when manufacturers can't improve their quality control.

The cross bar on the lower part of the frame would dig into my lower back. Gonna try adding some padding to see if that will help.
