Have you ever woken up in a warm tent after a cold night, and experienced that the walls feel almost wet? That’s condensation–a natural phenomenon that happens when moisture in the air hits the cold walls or floor of the tent and turns to liquid as it cools.

The air inside your tent can fill with moisture from several sources-- your breath, wet clothes and gear, or humidity in the air.

This moisture naturally condenses on cold surfaces and can collect under your tent’s mattress. If the tent is not properly dried out, mold or mildew can form on the underside of the mattress.
