A new tent experience – with a built-in “feel good” factor. Heimplanet’s The Cave offers the most efficient and stable structure – an inflatable geodesic dome. We call it the IDG – the Inflatable Diamond Grid. It is built by five identical pieces, which can be separated. This ensures stability even in the case of damages and an easy replacement. Pitching takes less than a minute – get it out of the bag, pump it up and you are ready to feel at home – with no parts to put together anymore. Its “round ground” design offers space for three to sleep and up to five to sit together. Due to the IDG, The Cave is stable in wind speeds up to 120 km/h.
