This is the one I use. http://www.huntersafetysystem.com/hss-lil-treestalker/ It's comfortable and easy as heck to put on. I used to use my old tree climbing harness that was always such a MAJOR pain in the rear. Everything all tangled up, in the dark it was near impossible to figure out which strap went where. I'd get so dang mad I'd just say to hell with it and go up without one.
