Cool clothes

The cooling vest covers the torso, where body heat is most concentrated. An ultra-lightweight, athletic-fit TechCool version for running or trail running; a cooling version to wear under a motorcycle jacket; and a high-visibility model in PolyCool™ or PCM for construction sites: three styles, one goal—to keep you in your comfort zone.

Our cooling T-shirts for men, women, and children combine thermal regulation (JadeCool™ or TechCool) with UPF 50+ sun protection against UV rays. Whether short- or long-sleeved, the fabric wicks away sweat without leaving a damp feeling on the skin. Available in white, blue, black, and gray.

Our cooling caps and UV-protective safari hats protect your head, face, and neck by lowering the local temperature. The safari hat model with a removable neck guard is ideal for extended exposure, hiking, gardening, and festivals, while the sports versions feature a cooling insert on the forehead designed for running.

The cooling towel is the fastest heat-relief solution in the range. Standard size for the neck and shoulders, XL size for extended coverage after exercise: it activates in seconds with a simple soak and can be taken anywhere—running, hiking, or to the office. Available in several colors including white, blue, black, orange, yellow, and khaki.

The cooling shorts provide complete lower-body protection during summer activities. Designed to wick away heat and sweat from the thighs—an often-neglected area—they pair naturally with a cooling T-shirt or vest for full thermal coverage from head to toe.

Neck coolers, cooling arm sleeves, bandanas: these cooling accessories precisely target sensitive areas of the body. The cooling neck cooler protects the neck, while the arm sleeves shield the forearms from overheating and UV rays—a practical asset for cycling, driving, or outdoor recreation.

G-Heat designs thermoregulation systems, not gadgets. Four distinct technologies, four tailored solutions to specific thermal challenges.

Put on the garment—that’s it. The multi-layer weave system regulates heat as soon as your body starts sweating. No water, no preparation: cooling is immediate and constant.

1. Soak the product in water.
2. Wring firmly: the fabric should not drip.
3. Shake (give it a sharp shake) to activate the jade microcrystals with a flow of air.
4. Put it on: you’ll feel the cooling effect in seconds thanks to the high Qmax rating. Reactivate as often as you like once the fabric dries.

1. Immerse the garment in water until the polymer fibers are fully saturated. This step takes longer than with JadeCool™.
2. Wring out firmly to remove excess water. The water remains trapped in the lining, not on your skin.
3. Put it on: the slow, controlled evaporation ensures long-lasting coolness, ideal for prolonged exposure to the sun.

1. Place the PCM inserts in the freezer for at least 2 hours.
2. Insert them into the designated pockets of the vest.
3. The temperature remains stable at 21°C or 28°C depending on the model for approximately 3 hours, without water or evaporation.

The duration varies depending on the technology. PhaseCool™ (PCM) inserts maintain a constant temperature for 2 to 3 hours. Evaporative products (PolyCool™, JadeCool™) provide cooling for 7 to 10 hours, depending on humidity, wind, and outside temperature. TechCool technology works continuously as long as you are wearing the garment.

Yes, but the technology makes the difference. Evaporative garments require airflow to work; they are effective under a vest or loose-fitting clothing. For drysuits, heavy uniforms, or closed motorcycle jackets, only PhaseCool™ vests are suitable. Dry cooling does not depend on ventilation.

No. The multi-layer design of our cooling products traps water in the technical lining, not against your skin. You feel the coolness, not the dampness. This is a common concern, and it’s precisely what our engineers addressed during the design phase.

For PolyCool™ and JadeCool™: rinse the garment under running water (water bottle, faucet, fountain), wring it out, and put it back on. The cooling effect returns in a few seconds. For PhaseCool™: place the inserts back in the freezer or a cooler. If you have a spare pack, simply alternate the sets of inserts for continuous cooling all day long.
