THis is the shelter. Better than any other poleless design out there. It's the weight/size of a bivy in your pack, but is totally spacious. Yes you need to be tough to sleep in a such a light shelter- there's no floor, or "tent" as you say, but this keeps you dry and protected- without having to lug poles. Only 1.8# w/out the pole, just string a line and hang the apex. The very best option if you have to carry your shelter.
