Omius Headband CrownPRO

Omius Headband CrownPRO (Omius Technology)

Omius Headband CrownPRO is a personal cooling headband based on amplified evaporative cooling.
It integrates 20 cooling pieces made of high thermal-conductivity graphite, each formed by
9 porous-structure micro-towers and treated with a hydrophilic coating that optimizes water
absorption and evaporation. Together, the pieces multiply by 5 the evaporation surface
of the forehead area they cover.

Cooling Mechanism

Water is absorbed into the porous graphite, where it has 5 times more evaporation surface.
When water changes from liquid to gas, evaporation absorbs heat (latent heat of vaporization)
and removes it from inside the pieces, which are in direct contact with the skin. This produces
a local decrease in forehead skin temperature.

Because the system is driven solely by water evaporation, the effect is sustained —not cold storage—
as long as three conditions are met simultaneously: wet pieces, direct contact with the skin,
and airflow over the pieces (generated by movement or, indoors, by a fan).

Usage Specifications

• Format: headband + 20 cooling pieces + carrying case
• Piece material: high thermal-conductivity graphite with hydrophilic coating
• Re-wetting: every 30–40 min during use, with water at any temperature
• Pre-cooling: no refrigeration or freezing required
• Compatibility: pieces are removable and interchangeable between Omius headband, visor, and cap
• Target users: endurance athletes (running, trail, triathlon, cycling, open-water swimming) training and competing in heat or humidity

Scientific Evidence

Local head cooling acts on cutaneous thermoreception and, through it, on perceived exertion.
Available evidence —including an independent study from Université de Sherbrooke published in
Journal of Thermal Biology (2024)— shows that the technology reduces forehead temperature
and improves perceived thermal comfort and perceived exertion in hot and humid conditions.

The same study found no reduction in core body temperature (rectal or mean skin) and no performance
improvement in a 5 km time trial. In line with Crown’s standards, Omius Headband CrownPRO is described
as a thermal comfort and perceived exertion management tool, not as a device that alters core
temperature or guarantees performance gains.

HOW IT WORKS — 3 Conditions for Cooling

• Wet pieces: soak the graphite pieces with water before and during use. Any water temperature works.
• Direct skin contact: cooling occurs through direct contact between graphite and your forehead, not air convection.
• Airflow: movement (running, walking, cycling) generates airflow that drives evaporation. Indoors, a fan is sufficient.

As long as these three conditions are met, cooling does not run out. Re-wet the pieces every
30–40 minutes to keep the effect at its maximum.

KEY BENEFITS

Cooling that doesn’t expire after 10 minutes

Unlike gel or ice bands that lose their cooling effect in minutes, evaporative cooling
is maintained continuously as long as the pieces are wet and you are moving.
Re-wet them and it continues.

Heat stops setting your pace

By reducing heat sensation on the head and perceived exertion, you feel more comfortable
in conditions where you would normally slow down. Less attention spent on heat, more on your race.

No cold logistics

No fridge, no freezer, no inserts melting mid-race. You only need water.
Cooling is recharged with a bottle or a spray.

Designed for heat and humidity

Works in humid environments as well: air always accepts some additional evaporation.
Useful from 15 °C for heat-sensitive athletes, up to extreme summer race conditions.

USER PROFILE

Designed for endurance athletes training and competing in the heat: marathon and trail runners,
triathletes, cyclists, and long-distance athletes who are particularly affected by high temperatures.
Especially useful in summer races, hot or humid climates, long sun-exposed sessions, double workouts,
and indoor training (treadmill, trainer) with a fan.

WHY IT BELONGS IN CROWNPRO

A protocol tool, not a standalone gadget

Heat management is part of performance, just like hydration or energy.
Omius Headband CrownPRO integrates into your Crown protocol for training and racing in heat,
alongside hydration and electrolyte strategy.

The technology used by the best

The same cooling technology seen on Olympic marathon champions and Ironman World Championship
winners in recent years, integrated by Crown into CrownPRO for your protocol.

Crown honesty about what it does

We don’t promise records. We promise what the evidence supports:
a cooler forehead, improved thermal comfort, and a more manageable perceived effort when the heat hits.
That’s how we do things.

INSTRUCTIONS FOR USE

• Before: thoroughly wet all 20 graphite pieces with water (any temperature). Place the headband with the pieces in direct contact with the forehead.
• During: move. Airflow generated by running, walking, or cycling activates evaporation. Re-wet every 30–40 minutes using a bottle, fountain, or spray.
• Indoors: use a fan to move air over the pieces and keep them wet as you would outdoors.
• After: remove the pieces and clean them with water and a small amount of dish soap. Store them in the carrying case.

CARE AND MAINTENANCE

• Graphite pieces are delicate by design: handle with care and avoid impacts with hard surfaces.
• Do not cover with your own cap during use: this can cause breakage and blocks airflow needed for evaporation.
• Pieces can be stored dry and re-wetted before each use.
• For travel, remove the pieces and transport them in the protective case.
• If a piece breaks, remove it by hand and replace it with a spare — no tools required.

FREQUENTLY ASKED QUESTIONS (FAQ)

How does it work exactly?
Through amplified evaporation. Porous graphite absorbs water and multiplies evaporation surface ×5.
As water evaporates, it extracts heat from the pieces in contact with the skin and cools the area.

Do I need to put it in the fridge or freezer?
No. It only requires wet pieces, skin contact, and airflow. Water temperature does not matter.

How long does the cooling last?
Indefinitely, as long as the pieces remain wet, in contact with the skin, and exposed to airflow.
In practice, re-wet every 30–40 minutes.

Why do I stop feeling the cold after a few minutes?
Because skin thermal receptors adapt. Cooling continues even if sensation fades.
Moving the band slightly restores the sensation.

Does it only work in extreme heat?
No. If you feel heat stress, cooling improves comfort and reduces perceived effort.
Some athletes use it from 15 °C upward.

Is sweat enough?
Usually not. Sweat helps, but optimal performance requires adding water.

Does it work in humidity?
Yes. Air always allows some evaporation, even in humid environments.

Can I use it indoors?
Yes, with a fan to provide airflow and regular re-wetting.

Do the pieces wear out?
No. The technology works indefinitely with proper care and cleaning.

Are the pieces fragile?
Yes, by design. Broken pieces can be replaced manually with spares.

Does it improve performance?
It improves comfort and perceived exertion. Independent research has not shown reductions in core
body temperature or guaranteed performance gains.
