ITW Webdom Web Dominator Molle Backpack Carabiner
These lil guys are great for any gear with 1" straps that need slack management. Traditionally duct tape is used as semi-permanent solution, but with Web Dominators you can get the holding power with dramatically better on/off speed and no sticky mess to boot. This way the slack can still exist to give sizing options, yet isn't dangling everywhere as a snag hazard or functionality annoyance. These also work great to hold down hydration tubes, wires, and other lightweight objects.
