* ''Tunnel'' tents may offer more usable internal space than a dome tent with the same ground area, but almost always need guy ropes and pegs to stay upright. These are almost always double wall tents. Sizes range from 1-person tents with very limited headroom up to 8 or 10-person tents with headroom exceeding 180 cm (6 ft). Tunnel tents have a low end profile making them great for high wind situations.
