BERG AirTracks are available in three versions: the Airtrack Home 300 and 500 are for recreational use. Both are 100 cm wide and up to 10 cm thick. The AirTrack Sport 500 is wider (140 cm) and thicker (20 cm), and is also suitable for experienced athletes. The material is extremely strong and lightweight. You can also use the pump to remove all the air from the AirTrack after you're done using it, and the AirTrack will hardly take up any additional space!
