Air tents (with inflatable support beams rather than metal/fiberglass rods) are a recent development in camping equipment and Hamburg-based Hemiplanet is a respected maker in the field. Their latest release is the extreme wind-enduring Nias 6-Person Tent ($1,100) as a possible solution to those who like to keep a lot of equipment (or a lot of family members) close inside.
Attached under this structure, the tent has two separate chambers on the ends with a vestibule area between. The sleeping chambers are removable and taking one out allows larger items, such as bikes, to be kept inside the tent. The Heimplanet Nias tent comes with all necessary stakes and tie-downs and a repair kit for quick field repairs in case of accidents.
