The world's first self-inflating boardbag. The Helium offers unsurpassed protection at a fraction of the usual weight. It uses the same technology as camping mattresses - all you have to do is add air by blowing into the valve. No need to worry about air pressure fluctuations on board airplanes, as the Helium stays inflated throughout the journey and is also ideal for shorter day trips. We have included an expandable shoulder strap with an elastic system that stays taut when not in use. At the end of the day, the Helium can be decompressed into a compact form and stowed away.
