Lost a dry bag off my WR when 2 ROK straps failed. Both failed right where the strap is stitched into the buckle. There is a little fabric that is used to sew them on to the stretchy part. That is what wore through. Both the rock straps were about a year old. Broke the buckles off and used the nylon webbing and knots to tie everything back on. It was embarrassing to watch the minivan I had passed a half mile back drive past as I was picking my bag up off the road. The Walmart dry bag did pretty good, only had a couple holes worn through. Replaced it next trip to Wally world for $6.99. Previously I lost a go pro and a long sleave shirt when I forgot to zip a back strapped to the rear of my WR. Shirt was found wrapped in the rear wheel. The go pro was in the bag lastt and was probably violently thrown out after the slave of the shirt found the wheel and was never found.
