i got a turkey vest real similar to that one. with the attatched seat, and the cross-chest sraps. it's a little more convenient that your typical vest. but not quite as comfortable i think. all the stuff in the back makes it hard to take cover quick if you're stalking a weary bird.
but it's a good setup. the only problems i ran into was it being uncomfortable with gear inside and leaning against a tree. but when a bird's in front of you, comfort doesn't really matter. it's all those other times that make the difference.
