I'm new to this forum, but I have experience with rags because that's all I have. I have too many hobbies and not enough money to go around so I got by the economical way and just bought 150 or so rags. My buddy and I were able to assemble them with one good night of work and they work great for me/us. My wife's handy with a sewing machine so she made me a camo sling which I ran a couple of 1" dowels through the sides. Resembles a wide stretcher. I can fit all my rags in it, tie the dowels together and easily carry them on my shoulder along with all my gear. Makes it easy for the times I go out by myself and have to walk a few hundred yard to my spots in the fields....As far as durability, I've used these now for about 7 years or so, and besides the few that the dowels came untaped, or the few that got holes poked through the plastic while putting them out in the dark, they're still working great. Sure, it'd be nice to have some full body shells, but these are all I have and they get us geese every year!
