i have friend with a carson 90 almost identical to carson 80. my son has the 80 model, i don't like the waist belt on the 80. the 90 had a thicker and better padded belt. with a better cinch system on the 90. is there anywhere i may be able to find some of the older style waist belts and retro fit to the 80. hopefully someone from jansport may read this but they haven't responded on their own site
John, I doubt if anyone from JanSport will reply on these forums. I think you would have better luck calling them at (510) 614-4000 and ask for customer service.
