What do you use to tie your safety vest to the tree?

I have a hunters safety system vest, and the strap that came with it is to short to maneuver around with in the tree, more times than I like to think about the strap would have been in the way to make a shot on deer if I wanted to take a shot.

I have made up a new tie down that is 5/8" nylon with a loop on one end and a carabiner tied on the other end, all told it is about 10'-0" long, which on the largest trees we have stands in should give me about 4'-0" of slack, more on the smaller trees.

The idea is to take the looped end wrap it around the tree, then run the carabiner end through the loop and clip it onto my vest.

Still not sure if this is the way I want to go, but for right now it looks like a better alternative than what I had last year.

What do you use?
