The Cocoon

The Cocoon is a highly efficient Altitude Simulation Tent. Used in conjunction with the Genie3 Generator its low volume enables high levels of altitude to be reached in as little as 10 minutes (2400 metres or 15.3% Oxygen). Its fully pop-up design means it can be easily assembled in less than a minute and folded back down into a neatly designed carry-bag.

Size: Adjustable size from Single Bed size (65 cm wide) up to King Size (180 cm wide).
Weight: 4kg

Genie3 Generator

The Genie3 Generator pumps Hypoxic (low oxygen) air into a sleeping or training tent via tubing and a silencing bag. This simulates a high altitude environment inside the tent of up to 4000m. By increasing the length of the tubing the generator can be kept in another room.

The Genie3 Generator embraces the latest developments in the reduction of sound and power consumption which has lowered the operating cost.

  • Simulated altitude: Heights up to 4000m (tent dependent)
  • Low operating cost (approx 50p per day)
  • 80-100 litres per minute flow rate
  • Electrical requirements: 312 W / 220-240 V
