Never heard of it, I'll have to do some research on that then. I envy Alameda Frank, he can do with a 3oz. tarp and no bug netting, the bugs don't mess with him. Here I'm trying to get under 12 oz. or so for a secure shelter. Everyone wants so much money. By the time I get all the pieces here, I may be better off with the Zpacks solo Hexamid with netting and beak.
