I was trying to make my first hennessy clone and figured i was going to make it as light as possible. I saw ppl making some out of 1.1oz, but non out of 0.9oz ripstop(the lightest material i could find). So i figured i would try it out. I spent two nights in it this weekend and it sleeps better than my real hennessy. I still have the rain fly and bug net to make and maybe some sag adjustments are in the near future but besides that it was awesome!
