Used for nearly a week but it was great weather. Was hoping to see how it did in some rain, but I have no reason to believe this cover will not shed the rain like a champ. It certainly kept the tent cool in tandem with the Vestibule. I had read other reviews about difficulty to put on, but Kodiak must have made an improvement to one side of the cover before I bought because it was super easy and it came with instructions. I also watched some YouTube videos before I purchased. I do not regret the purchase. I am still learning how to fold it best after use though and it is stiff.
