I have 2 of 3p. Used it on a few backcountry hunts (Montana and Colorado) and a bunch of family camping trips. On one particular family beach trip, my wife and I were split between the 2 tents with our kids. A big thunderstorm with hellacious winds and tons of rain came through the campground one evening. My wife and I were texting each other as we watched the water level slowly rise praying the seams would hold on the tent bed. The water got to about one inch to the bottom of the doorway then thankfully the storm subsided. Not one leak! Since that experience, I have been through a few other rainstorms and one surprise snowstorm. I have complete confidence in those tents.
