I don't have any experience with them, but have given a little thought to making one. I think a hooded sweatshirt with pants would work great. Just slice and stick them with rags. It seems that you could make adjustments so that the bowstring wouldn't be interfered with. I would cut the rags short on the inside of my bow arm and on my chest. The rest could be left long, but I think you'd definitely have to shoot the bow some while wearing it to fine tune the gettup. I havn't given any thought to the hood, but figure that it could be handled the same way, or even leave the rags off on that side of the head. Figure I'd give it a try this winter and see how it works out for next season.

Make them sharp and shoot them straight, or leave them home.
