Folding Camping Cot Outsunny Multifunctional ...... is it just cool, or is it worth it. 

I bought the two person version of this. Used a screwdriver to poke 4 holes in the cot; two towards the middle for each side. The rain does catch but the cot is “water proof” and so runs down and through the holes to the ground so rain isn’t actually an issue

you could use a tarp as a roof.

Would not buy
