The Cave – the Inflatable Tent Home Planet

“The Cave”, the inflatable tent home planet, was presented at the OutDoor 2011. The futuristic-looking 3-person tent consists of an inflatable frame structure, inspired by the molecular structure of a diamond. The construction principle followed by a geodesic dome.

The first idea to the home planetfounder Stefan Clauss and Stefan Schulze Danan was created in the summer of 2003 in Portugal, while on a surfing holiday. They planned to construct a new tent design that will build up quickly and easily, even during bad weather or at night.

The result is a tent, where design and function to a concept merge, which uses air as structural. 5 double-walled, separate air chambers made of thermoplastic polyurethane (TPU) form the geodetic framework. Build, they act as an air cycle, which can be divided after filling in 5 separate air chambers . This patent-pending design makes the tent “The Cave” flexible and strong. “The Cave” is even wind speeds up to 120 km/h withstand. Inner tent and flysheet are hooked to this inflatable structure. The tent weighs 5.4 kilos and is already inflated after 60 seconds (when using an air pump) and ready for use. The assembling of individual parts or hooking the tent cover is not necessary. The round floor plan offers 3 bedroom or 6 seats and is just as quick done like the building.

A really awesome concept by which we could even convince us on the OutDoor. The tent is available within seconds and makes a stable impression. Even if one of the 5 Chambers of the frame structure loses air the tent remains stable. For transport, the air is simply drained and the tent is completely stowed without releasing the “linkage” or hang the inner tent in the stuff sack.
Certainly, “The Cave” not for lightweight trekking is suitable, but for camping trips with frequent relocation, it is perfect.
