They performed well on our first family outing. We had a little of everything: wind, rain, chilly nights, sun. Even though I didn't have it fully guyed down, wind was not a problem. I wish the flaps covering the vestibule screens had zippers or hook-and-loop closures. They kind of just sag, probably to allow air-flow through the well-ventilated roof. They must do the job because no wind got into the tent. As a precaution, I seam-sealed the seam around the perimeter of the floor. I had a very small amount of leaking in a backyard test. Overall, lots of room and the steep sidewalls make walking around this tent like walking around your living room.
