Cooling products: how do they work (and why are they changing everything)?

Produits rafraîchissants : comment ça marche (et pourquoi ça change tout) ?

Romane B. |

You know that heat that sticks to your skin in the middle of summer? The kind that makes you sweat profusely before you even start your activity? That's exactly why cooling products exist. At G-Heat, we design simple, effective, and technological solutions to help you better cope with heat waves. Whether you're working out, at work, or just out for a walk, there's a solution for you. But how does it work, exactly? And why does it make such a difference? Follow the guide.


What are cooling products?

Definition and types

A cooling product is a piece of clothing or accessory that helps your body regulate its temperature, especially when it's hot. Their purpose is to limit overheating, prevent heat stroke, and improve comfort, performance, and recovery.

There are two main categories:

  • Passive products, which use technical materials without external activation.
  • Active products, which store cold (using gel or phase-change materials) and release it on contact with the skin.

All these products are reusable, self-contained, and much more practical than a fan or a bottle of ice-cold water when you're working hard.

Examples of cooling products

The G-Heat range includes:


Why the body overheats... and how cooling products can help

When you are active, your body naturally heats up. To prevent overheating, it sweats, dilates blood vessels, etc. But these mechanisms have their limits, especially when:

  • it is very hot
  • the air is humid or stagnant
  • you are wearing closed equipment (helmet, PPE, etc.)

This is where a cooling product makes all the difference. It acts as an amplifier of the body's natural thermoregulation mechanisms to help you:

  • maintain a stable internal temperature
  • reduce fatigue
  • avoid heat-related discomfort


The technology behind cooling products

Cooling textiles and thermoregulating materials

So-called “passive” products work without any special activation. They rely on specific materials that facilitate breathability, moisture evaporation, and heat dissipation.

At G-Heat, two flagship technologies illustrate this approach:

  • POLYCOOL™, used in the cooling cap, promotes maximum ventilation and quick drying.
  • JADECOOL™, integrated into the cooling towel, uses the natural properties of jade to lower the perceived temperature.

Active cooling technologies: gel and phase change materials (PCM)

“Active” products use elements that can accumulate cold and then release it. Two approaches are often combined:

  • Cooling gel, contained in flexible pockets, to be placed in a cool place before use.
  • PCM (Phase Change Materials), which melt to absorb body heat and then solidify to release it.

These technologies are used in our cooling vests, neck coolers and safety accessories.


Cooling technologies developed by G-Heat

POLYCOOL™: breathability that keeps you cool

An ultra-breathable polymer fiber fabric, ideal for sports, construction, and urban travel.

JADECOOL™: the power of minerals for comfort

Jade microparticles for gentle, long-lasting freshness on contact with the skin.

PHASECOOL™: adaptive technology

Used in particular in our cooling vests, it adapts in real time to the body's thermal needs.


How do you activate a cooling product?

Step 1: Easy activation

Wet, wring out, shake. It's ready. All our products are infinitely reusable and UPF50+ UV-resistant.

Step 2: Direct contact with the skin

Wear your vest, towel or neck gaiter to activate the cooling effect.

Step 3: Enjoy the coolness

You can now move, work or relax without suffering from the heat.


The different applications of cooling products

Cooling hat: protection and style

The cooling hat protects your head, neck, and face while providing continuous cooling.

Cooling vest for outdoor activities

The cooling vest covers the upper body and is ideal for professionals and athletes.

Cooling towel: simple and effective

The cooling towel is perfect after exercise or during breaks, and can be slipped into any bag.

Cooling accessories for targeted comfort

Discover our neck wraps, caps, headbands and cushions, designed to suit all situations.


Benefits of cooling products

Improved thermal comfort

You breathe better, sweat less, and stay active longer.

Impact on physical performance

You gain energy and concentration, whether you're at work or in the middle of a workout.

Suitable for extreme conditions

Thanks to JADECOOL™ and PHASECOOL™, you're ready to face the heat wave without heat stress.


How to choose the right cooling product?

Criteria to consider

Importance of additional cooling packs

Use our refillable cold packs to prolong the cooling effect of your vest.
