I have both, Seat o the pants (purchased) and the one that just came with my Summit treestand, the big difference is the way it attaches to your lanyard. The one that comes with your Summit has a "Rams horn" type hook (basically a curly q kinda of set up) and the purchased one has a true climbing carabeaner (sp?) I prefer the carabeaner type, but both are great and give me alot more confidence when I shoot. What G2 shooter said is true though, If you wear a hood the strap comes out of you hood about where your ear is. I dont know how that would be if you fell, i.e. jerking your head around, and I dont like to wear it over top of my coat, too hard to get into pockets and extra things to clink together.
