Two's company, three's a crowd - not with the Heyerdahl. The tunnel shape maximises space, so it won't feel cramped and crowded. Plus with just two, equal-length poles weight is kept to a minimum and it's easy to pitch. The vestibule has room for your backpacks and the zipped mesh ventilation windows in the canopy and three vents in the flysheet reduce condensation build-up. If you want to take things back to basics, you can use the flysheet on its own like a tarp providing lightweight rain protection. Named in honour of 20th century Norwegian explorer, Thor Heyerdahl, this tent is built for exploration.
