Snowcap Sleeping Canopy
The Snowcap sleeping canopy is a small enclosure that allows you to sleep at high altitude. The Snowcap concentrates reduced-oxygen air directly over your pillow, instead of enclosing your entire bed inside a plastic tent. The unique design helps keep you cool and comfortable.
The Higher Peak sleep canopy reached full altitude in less than 5 minutes, compared to 4.5 hours for the CAT-315, 8 hours for the CAT-430, and 1.7 hours for the Hypoxico Deluxe Bed Tent...The humidity inside the Higher Peak sleep canopy was 48% compared to 70% inside the Hypoxico Deluxe Bed Tent and 64% in the Colorado Altitude Walk-in Tent.

How the Snowcap Works
The Snowcap features a canopy with a weighted bottom edge that rests gently on your upper body and contains the low oxygen air. Fresh hypoxic (low oxygen) air flows across your face and exits through small gaps around the edge of the canopy. The airflow can be redirected for maximum comfort. Since the low oxygen air is flowing outward, there is no opportunity for regular air to come in. If you lift the canopy during the night, either by getting up or just rolling over, you will get a shot of outside air, but it will quickly be brought back to altitude. If there is a power failure, air from the room can enter through the small gaps around the edge of the canopy, keeping you safe and preventing suffocation.
