I have a pair of bibs from 2016 or 17 that the stitching for one of the straps pulled out. It wasn’t stitched very well, but it happened a couple of years ago and I’ve just been using them with one strap ever since. I thought I’d try a warranty claim and they didn’t hesitate to put a new pair in the mail for me. I didn’t have to send the old ones back or pay any shipping charges.
It was a good experience that was pretty painless so I thought I’d share.
