Technology FAQ

How does the technology work?
When water or sweat evaporates on the surface of the skin it absorbs heat and cools the body. The amplified cooling effect of the Omius technology comes from water being absorbed into the cooling pieces where it has 5x more surface area for evaporation. The transformation of water from a liquid to a gas on the surface of the graphite pulls heat from the inside of the cooling pieces which are in contact with the skin and thus cooling the skin. Because the cooling effect is driven solely by water evaporation the effect will continue indefinitely as long as the cooling pieces are wet and have airflow across them.

What is the material in the cooling pieces?

The cooling pieces are made of a highly thermally conductive graphite coated in a hydrophilic coating that optimizes the uptake and evaporation of the water that powers the cooling effect.

Do I need to put the cooling pieces in the freezer?

NO! The only requirement for amplified cooling is that the cooling pieces are wet during use, sit in direct contact with the skin and are uncovered so air can flow across them to enhance the evaporation.

For how long does the technology cool during use?

The cooling pieces will continue to cool indefinitely as long as they are wet, sit in direct contact with the skin and are uncovered so air can flow across them.

Why do the cooling pieces not feel cold after I have worn it for 5 minutes?

The headband cools via direct contact of the skin with the graphite. After about 5 minutes, the thermal receptors in the skin stop noticing the temperature gradient between the warm skin and the cooler graphite and instead perceive it as the “new normal”. But the cooling effect persists and can be detected by moving the headband slightly so the graphite comes in contact with skin that has not yet adapted to the “new normal”.

Does the technology wear out?

No. The cooling technology will work indefinitely as long as it is maintained with regular washes and care in handling.

Do I need to keep the cooling pieces wet at all times?

No. The cooling pieces can be stored dry and then re-soaked before each use.
