The airspeed mechanism is a patented pole system which we are more proud. It is composed of 25mm Diameter Aluminium poles. You simply lift the central frame hubs, and pull the middle joint of the 4 legs gently, then the whole tent is up; Pull the centre central frame hubs apart and the tent collapses, to be put away quickly. Very easy and quick. The airspeed tent is usually used for large family tents or 4×4 vehicle tents. We have no doubt that the airspeed tent is the quickest, strongest, most stable and comfortable tent in the world.
