In my experience, portability is the major limiting factor in the use of any tent. How much can you carry in your hands or on your back, most of the day, every day? This is why the U.S.A. army infantrymen each carry only half of a tent. The lighter materials are either too weak for daily use or too expensive. Donated tents are available to the homeless in many cities of the U.S.A.. These tents often end up as litter in the vacant lots where they are used and then abandoned. Blankets are more valuable to people on the move without wheels. Combining tents and sleeping bags, or just making sleeping bags that are waterproof, has been done. Can we find some material to replace the cheap plastic tarp, that is lighter and stronger and no more expensive? Creating a tent for all seasons and sites does not seem feasible. I will look for the cost and strength of reflective plastic in tent size sheets.
2 mil Mylar reflective plastic film is sold in 25 foot by 50 inch rolls for about $17 per roll.
