When I pull on the strap the D-ring wants to twist and it doesn't tighten. It seems to be only one side. I looked closely at both sides and the other side has a different looking wider webbing. The D ring on the bad side has 1/2 of play up and down while the good side only moves 1/8 inch or so. Headed out in the morning with my girls all weekend for their first backpacking trip so I'll call the shop on Monday. Anyone have a quick fix for this? I know it's gonna drive me crazy if it does it all weekend.
