I have had a 12 by 12 with the vestibule for years using it for moose hunting in northern Maine. I just purchased the 12 by 16 with vestibule. Vet we’ll build product screens, zippers, canvas all high quality. I have never been cold or wet in this tent and heats very easily with a small wood stove. Compared to outfitter wall tents this is the best bang for the buck.
