Can't get enough of these!
I have quite a few of the 60cm slings and they are so, SO useful! I use them for long draws, rack slings in a pinch, belay anchors, draw extensions, anything you need an extra foot or two really. You can't go wrong for the price, either!
(note, i learned while SCUBA diving that nylon straps settle when wet, meaning they stretch. just bear that in mind when tying these in wet conditions!)
