Cuben = Low Condensation?

My worst experiences have been with Sil-nylon. Same basic design but too many other variables for me to track.

What a coincidence.
I just finished some exhaustive umbrella tests and came to the conclusion that white polyester offers better rain protection than black nylon.

Hi John, different shelters though. The Hexamid is pitched high, while the Six Moons is pitched very low. The Wild Oasis has perimeter mesh which also blocks ventilation.

I think you nailed it Dave. That is the reason I have avoided the mesh on my subsequent shelters.
