I have a complete two person portable mountain high ox demand system for sale.  The bottle is aluminum, kevlar wrapped capable of 3,000 psi. It is in a nice carry on bag. I have cruised often at 13,000-15,000 and it works great. I also have a 4 foot high O2 bottle and filler hose to refill the portable bottle My wife and I used one bottle from Seattle to Chicago and back no problems.
