The seams are not sealed. It does have a polyurethane coating and the rain fly will also protect from moisture.

The fly is factory sealed and urethane-coated. The sidewalls that are exposed to the weather are also. The floor tub is woven poly tarp material, which, although heavy, is waterproof and rugged. In several days of wet camping, it leaked a small of water around the rear window zipper, but certainly was not flooded. It was far dryer in these conditions than my other tent, a two-person Eureka Apex. The size and vertical walls make it simple to stay out of contact with the fly, which can lead to getting wet from condensation.
