The frame of the device has got another amusing name, ‘Inflatable Diamond Grid’ – or IDG for short – and takes a minute to pump up. It works fabulously well in stormy weather and because the frame is sub-divided into five sections, even if one part gets damaged it stays solid. Forget camping in Sai Kung, you could erect this tent in Tripoli.

Even more pertinent to the conditions in Hong Kong, however, are The Cave’s five ventilation openings that provide airflow from bottom to top. All in all, we’ve never heard of a tent as technical as The Cave - check out the specs of the grid for instance - so if you’re a keen camper or just plain paranoid then it’s the one for you.

Camping colossus.
