Anybody use Tyvek as a floor for a canvas tent? I have a 13x15 7oz canvas tent that is floorless. I’m looking to make or purchase a light weight floor for it that will work well... anybody have any experience with Tyvek? I know it’s water proof 1 does it breath at all- not sure if this will creat any condensation in the tent? Any other products out there that might work well?
