I have the exact SOP "Supreme" model that Bowsite tested in the link Barry gave you........quite simply the thing is fantastic.
The buckles are quick and simple to use, no threading of straps etc....just clip and zip.
Extremely comfortable and secure...you just FEEL safe wearing it.
The pouch in the back allows you to carry your safety rope and any small gear you need as well so it's right there with you.
I used mine setting stands this summer and it's the best I've used by a long shot.

It's pricey as far as harnesses go at around $90-100 but if you feel your life isn't worth a $100?????..............[:-]
IMO every hunter on this board who hunts from a treestand should own this harness. I like to come home at night in one piece so I am only going to trust my well being with what I feel is the very best available.

You guys who hunt with nothing, or hang stands with nothing, or choose to use a cheapy harness or waist strap or God forbid.......a rope only.[:-] I guess you guys have nothing or nobody to live for right?
