So I'm guessing the rope slides into itself somehow from looking at the pics for adjustment purposes?
And you carry SIX sticks in with you? What on earth for?

Hollow outer rope with smaller inner rope...when pressure is applied to the outer rope, it stretches tight against the inner rope, preventing it from slipping (sort of like prussic knots, not in design, but in how it moves freely until pressure is applied and then it cinches tight) the inner rope slides freely in and out allowing you to adjust length....my only concern is it seems like it would be really hard to ever get these bad boys cinched down tight enough against tree, perhaps it isnt needed.
They are like those things found at kids fairs...you stick your finger in just fine, but when you try to pull it back out it just cinches down tighter on you, the more pulling force the harder it pulls back.
The guy on AT patented them a while back and is selling them now, forgot his name. Username starts with a Z though i think.
