The Dometic AIR Shelter 400 is very quick to pitch. Inflate in no time at all thanks to the supplied hand pump. To set up simply peg the four corners and inflate from the two inflation points on the outside of the shelter. On the underside of the shelter, tensioning straps ensure a square shape is maintained while durable fluorescent guylines and supplied pegs keep the shelter stable. The Air Shelter covers an area of 13 x 13 feet and come standard with four removable side panels. These side panels are fixed by means of an easy ring-pin system. The shelter material is our premium Weathershield™ 6000, a high quality material featured on many of our tents.
