I have been reading about a great product--anyone use this?

Saw something similar on Cabelas website under treestands or climbing treestands. I think it was called a tree sling or something like that. The only concen I would have would be getting turned around to shoot a deer coming in from behind you, or even directly in front of you. Just thinking that if you moved, your clothing/pants are going to rub on the tree and be noisy? Just a thought.
