We've edited this original post to show the most up to date version of this sling project. It's based on our Accelerator Sling and uses the same collapsing loop design but with a different adjustment mechanism. Instead of using a single buckle this one uses a dual buckle system, to create an optimal webbing path. It does not require any sort of pull tab to operate; simply slide the buckles to the desired position and that's it. Like other designs on the market it uses friction created by weaving the webbing through the buckles, the difference is that because two buckles are used instead of one, they "loosen" and slide more freely when adjusted, making it very fast and smooth. The prototype pictured below is in MultiCam and uses ITW hardware. It weighs only 80g or 2.8oz!
