ALTITUDE TENT!!! This tent is a Hypoxico model that fits over a queen size bed and nightstand, and has been used for only six months! It comes with a high altitude adaptor that allows the tent to reach altitudes of 12,500 ft. Also included are the original manuals and an oxygen monitor that allows the user to check the actual altitudes while in the tent. All of this now retails for $7,600 but I am willing to sell mine for $5,300 and shipping is FREE! Please email all inqueries
