Hot, heavy, bulky, and pretty loud when on a stalk. I have one, and have used it in the past, but mostly for predators or photography. I would not recomend one for bowhunting. just too much to carry around.
If you do use one DO NOT SMOKE IN IT!!!! if your a smoker. Every year somebody dies, or gets seriously burnt in one when the smoke lights up the burlap. Lots of guys in long range tac rifle comps wear them and its usually at those outings i hear about a guy standing around smoking, and poof! they go up fast.

When in doubt, floor it.
