I once had the perfect item! It was made by Gerry back when they made backpacks and stuff. It was basically a good size tarp of light coated ripstop nylon. On the long edges it had a separating nylon zipper and on the short sides it had extra material forming an overhang for the doors. It had mosquito netting at each end that was attached behind the overhangs. The netting was large enough to roll it up and fasten with ties or let it down to cover the entrances. If you zipped the sides together, it made a one man tent with a floor and bug net doors. If you unzipped the sides, it would make a 2 man shelter without floor and the bug net still covered the door areas. You could also use it as a simple tarp to cover a fairly large area, with the bug net rolled out of the way, of course. It had numerous nylon ties for pitching and staking it down and was very small and light. Really versatile!! I used to carry this and a mil poncho to cover any situation, short of glacier climbing trips! Weight was about 1 lb. I would give anything to have another one!! Came in green, brown, orange too. Any manufacturers out there???
