From Pathfinder Wiki
A good tent will be made of breathable material that allows the moisture to pass through (such as a nylon mesh), and there will be a rain fly on the outside to keep rain out of the tent. Water vapor passes through the mesh and condenses on the fly. It then runs off the underside of the fly and drips off the edge outside the tent.
