I checked out the website. I'll chime in...as someone who has spent several thousand hours in trees over the last 17yrs, I can gaurantee that is going to be one of the most uncomfortable setups around. The straps under the buttocks and through groin are way too slender to be comfortable, they'd be digging in in oh..say...15 minutes or so, then you'd be readjusting your position all the time after that. I've hunted in this fashion several times but with professional climbing gear. My saddles all have two "D" rings on each hip, then when you lean back, your body weight is naturally centered and you are very steady. Also have two lower "D"s that when you are tied into, it forms a seat so you can actually sit down in the saddle. With the Green's single tie in in the middle, one would be very unstable, swaying left and right and I'm sure that wouldn't make for a very steady shot. Also, the harness itself makes no provision for actually getting up the tree, so I don't see any benefit to this over a regular tree stand strap! The best setup like this I've seen is a tree climbing saddle made by a company called Petzl, they have been making rock climbing equipment for years and have recently begun to manufacture tree climbing saddles. They took their knowledge of lightweight manufacturing neccessary for rock climbing and together with a few of the big dogs in the tree care industry created a line of saddles, harnesses and ascension/descension equipment that is just amazing. If you're really interested in hunting in that fashion, I'll get some info together and post it here. With the items they have available, for about $200-$300 you can get set up with a kit that will allow you to throw a rope over the limb of your choice, ascend that rope very easily, secure yourself very comfortably and stably to the tree, then when finished descend smoothly and safely to the ground. It would all fit in a daypack and weighs about 5 pounds for all of it.
