How does the Ohnana stay cool?
The Ohnana Tent uses a special aluminium coating which reflects up to 90% of sunlight. The coating prevents the tent from absorbing infrared light, which is the light frequency responsible for heating up your tent to uncomfortable temperatures. Of course, we can’t put all the blame on the sun; you are responsible for your tent heating up as well! Additional heat radiates from you and your camping companion’s bodies. This is why we use airgaps and the Ohnana Fan to dispense as much of the generated heat as possible.
How much cooler is it?
The Ohnana Tent stays much cooler than conventional tents: at an ambient temperature of 25 ºC or 77ºF regular tents will heat up to 41ºC or 105ºF, while the Ohnana stays a comfortable 27ºC or 80ºF. Below you scan see a graph showing measurements we did on a regular summer day. The red line - representing a $250 regular tent - quickly heats up immediately after sunrise. By reflecting most of the sunlight, the Ohnana stays much closer to the outside temperature. The exact difference depends on the climate you camp in: the brighter the sun, the bigger the difference the Ohnana will make!
Think of it this way: normal tents work much like a mini-sauna, where both your body and the sun’s heat make the inside temperature rise to scorching levels. The Ohnana Rayve does not feature active cooling, like a refrigerator or AC-unit, but instead reflects and dissipates heat. As a result, sleeping in the Ohnana feels more like sleeping outside in the shade than to sleeping in a normal tent.
