Took this tent to the Big Bend National Park in Texas. Did a three day hike. On our second night we were on the South Rim trail in a primitive campsite. Weather was glorious until a thunderstorm came through just after sundown.I was worried.As I lay there listening and seeing the heavy thunder and lightning, hoping that I would stay dry, I heard my companion in his tent ( NOT a Big Agnes ) shout.."are you dry?"...I was..he wasn't!...As I opened the zipper I saw that the water was within a couple of inches of the rim of the tent base. He carefully climbed in. We slept as much as we could through the night. The storm continued for hours. As the first light broke..we looked around in the tent...totally dry!!..We were amazed. I would take this anywhere. The dual doors and multiple vents allow for amazing flexibility and are perfect for airing the tent whatever the conditions. This is the best tent I have ever owned.
