i have a large Baker tent made from Silnylon and it's held up in very bad weather.it's sort of slippery so i never thought od using it for a ground cloth.i use a space blanket.

here is that shelter after a heavy storm.i woke to find a very bad thunderstorm sweeping across my camp on a open point on a lake.the shelter had pulled the stakes and was flapping and pulling on the main tie-outs.i cut the lines,pulled it down to cover the gear that was inside and put rocks and branches to hold it down and got back in my tent to get out of the driving rain.i took this photo later when things cleared and i was getting ready to set it back up..nothing ripped---
