We packed a family of five into this spacious dome, and no one had to jostle for room. Its 65 square feet of floor space and five-foot eight-inch ceiling height feel castlelike if you're used to Lilliputian backpacking tents. Two huge doors and 12 organizing pockets make for easy group living, and the three-pole design pitched quickly even when Dad had to do it alone. As sold the Big House doesn't have a traditional vestibulewhich saves weight and bulk should you want to schlep it to a base campbut makes it best suited to mild weather (even so, we slept through a deluge in southern Utah and had no complaints). Add an optional, enormous vestibule (52 square feet, $100) for extended foul weather. 11.3 lbs; bigagnes.comBonus: A welcome mat adds a touch of unexpected civility.Bummer: Storing wet gear is a hassle without that add-on vestibule.
