High Altitude Adapter - HYP and fits on all bedsThis adapter increases your generator's max altitude from 12,500ft 3800m to 21,000ft 6400m. When using the High Altitude Adapter, increasing the simulated altitude will lower the flow rate (hypoxic air output) of the generator. For this reason, you may not achieve your desired O2% when sleeping in a larger volume space such as the Deluxe Tent. For best results, sleep in the Head Bivy when using the High Altitude Adapter.
