Learn about iMatJet®’s unique technical refinements Our development team worked tirelessly on the optimal geometry and perfection of the 3-chamber system. Compared to common air mattresses (material thickness max. 0.2 mm PVC), the iMatJet® is made of much more robust material (lower chamber 1.0 mm, upper two chambers 0.6 mm) and is therefore reminiscent of an inflatable boat in terms of stability. It is equipped with three holding/carrying handles and two bottle holders. Three bayonet locks (as used on SUP boards) ensure that no air can escape from the valves.
