Key Takeaways 💡
The best choice of 2026 cooling clothing from G-Heat comes down to one question: Will your situation allow you to wet the garment, or not?
- Sports and intense physical activity: the TechCool™ sports T-shirt, which activates automatically with your sweat and keeps your skin dry.
- Instant cooling relief: the JadeCool™ cooling towel—just soak it, wring it out, and slap it on.
- Long-term exposure without access to water: the PolyCool™ cap or vest, which can be filled with water once and provides cooling for several hours.
- Under full-body gear: the EVO PhaseCool™ arm sleeves, the only temperature-controlled dry technology.
- Kids and family outings: the kids’ UV-protective T-shirt and the 360° protective hat.
All four technologies can be reactivated indefinitely, and the UV-protective fabric blocks over 98% of UVA and UVB rays on covered areas.
The comparison chart of the 20 models is right below, filterable by use.
The right technology matters more than the right product
The selection of cooling clothing has never been so extensive. That’s precisely what makes the choice difficult.
A T-shirt, a cap, and a pair of arm sleeves can all promise cooling but have nothing in common. One works with your sweat. Another needs to be soaked. The third stays perfectly dry. Choose the wrong one, and you’ll end up with a garment that never activates—or one you have to re-wet every twenty minutes.
At G-Heat, four technologies make up the cooling lineup. They aren’t ranked from worst to best—they’re designed to meet different needs.
- TechCool™, dry coolness: a weave that works with your sweat continuously, without ever getting the garment wet.
- JadeCool™, maximum coolness: JadeCool™ technology uses micro-crystals of jade for an immediate cooling effect that can be reactivated in just a few seconds.
- PolyCool™, long-lasting coolness: fibers that store water and release it slowly to maintain constant coolness for several hours.
- PhaseCool™, stable temperature: a material that provides cooling without a single drop of water, ideal for wearing under outer layers.
The right choice therefore depends on four factors: whether the garment can be wet, the duration of exposure, the intensity of the activity, and whether you’ll be wearing additional layers over it.
This comparison covers all 20 items in the line, detailing for each one the technology used, the activities it’s designed for, and what it can do. The goal: to help you know which one to choose before opening a product page. We’ve been designing thermoregulation gear since 2017, and this approach to making choices based on specific conditions is the one we use ourselves.

Choose based on your sport or activity
Sports and intense exercise
During exercise, sweat quickly becomes uncomfortable. That’s exactly where TechCool™ comes in: the fabric activates as soon as your body sweats, without any effort on your part. Just put it on—that’s it.
Three pieces are all you need for a workout—all lightweight and ready to wear.
- The men’s cooling sports T-shirt or its women’s version—the essential top.
- The men’s cooling sports shorts or women’s version, perfect for long workouts.
- The cooling sports headband, for your forehead and temples.
The result: cooling that intensifies as your effort increases, with no fiddling required along the way.
For breaks, the G-Heat JadeCool™ cooling towel takes over: soaked and wrung out, it cools the back of your neck in seconds. On long outings in the sun, the PolyCool™ cooling sports cap lasts several hours on a single soaking.
Family, Vacations, and Everyday City Life
Between commuting, running errands, and unexpected events, heat builds up without us even noticing. Here, the priority isn’t performance but simplicity and sun protection.
For kids, the kids’ cooling UV-protective T-shirt meets both needs at once: staying cool and a fabric that filters out more than 98% of UVA and UVB rays on covered areas. For adults, the women’s cooling UV-protective T-shirt and its men’s version serve the same purpose.
For the head and neck, four accessories help protect the most exposed areas.
- The cooling UV-protective hat, for 360° protection of the head and neck.
- The cooling cap, the easiest style to slip into a bag.
- The XL cooling towel, for long breaks, whether at the beach or in the park.
- The cooling bandana, the most versatile: on the head, around the neck, or under a helmet.
These four options are particularly effective on full-day outings, when heat-related fatigue can set in without warning. The towel, however, isn’t something you wear: keep it in your bag for breaks—it’s the quickest way to help a child cool down when they’re overheating.
Motorcycle and Bike Rides
Numb hands don’t react quickly enough. Overheating under a jacket has the same effect on alertness.
Here, maintaining alertness is directly tied to safety. Three pieces of gear address this need.
- The JadeCool™ cooling neckband, worn under the helmet on the most sensitive area.
- The EVO PhaseCool™ cooling armbands, the only solution in the line tested for use under full-coverage clothing: they stay dry, so nothing sticks to your jacket.
- The gray PolyCool™ cooling vest, which slips under your jacket and creates a cool microclimate for several hours.
Static Exposure and Outdoor Work
In a stationary position in direct sunlight, the problem is no longer intensity but duration. A garment that cools you for twenty minutes is useless if you’re outside for six hours.
PolyCool™ is designed for this, and it’s the technology most often chosen by professionals working in highly exposed conditions.
- The reflective cooling vest: a high-visibility vest that combines long-lasting cooling with safety on the job site.
- The UV-protective safari cap: it protects the back of the neck, the area where heatstroke most often occurs.
For a stationary job in direct sunlight, these two items significantly reduce the fatigue accumulated over a full workday.
When the environment prohibits any moisture—such as in a professional kitchen or a cleanroom—PhaseCool™ becomes the only viable solution: controlled temperature, no water, and two to four hours of battery life. The EVO cooling sleeves are the entry point to this technology and the only option that never gets wet.
If your workstation allows for moisture, the men’s long-sleeved Anti-UV cooling T-shirt covers the forearms—an area that short sleeves leave exposed all day. It uses JadeCool™ technology, so it can be soaked and wrung out like a towel: just two simple steps to incorporate into your morning break, and sun protection is maintained on covered areas, whether dry or damp.

G-Heat Cooling Clothing Buying Guide
“Customers often ask us what our best technology is. There’s no single answer to that question. A chef and a trail runner face different challenges: one can’t tolerate moisture, while the other constantly produces it. We don’t sell a hierarchy—we sell four solutions to four challenges.” ”
Gwenaël Fournet, G-Heat Product and Innovation Manager
How to Choose Your G-Heat Cooling Garment?
Four questions are all it takes to decide. We ask them in this order.
- Can you get the garment wet? No: TechCool™ or PhaseCool™. Yes: JadeCool™ or PolyCool™.
- How long will you be without access to water? Long exposure without access to water: PolyCool™, two to six hours. Under protective gear: PhaseCool™, two to four hours.
- Will you be exerting yourself and sweating? Yes: TechCool™, which becomes more effective as you sweat. No, static activity: PolyCool™ or PhaseCool™.
- Is the air saturated with humidity? Yes: rule out JadeCool™ and PolyCool™; keep TechCool™ and PhaseCool™.
💡 Our expert advice: don’t look for the most powerful technology—look for the one that addresses your main challenge. A TechCool™ T-shirt worn without exertion will feel less cooling than a soaked JadeCool™ towel, and that’s not a flaw—it’s how it’s designed to work. The most effective combination often involves pairing two technologies: a garment that works continuously and an accessory for sudden heat spikes.
What are the criteria for choosing cooling clothing?
Beyond the technology itself, four criteria make a difference in real-world use.
- The Qmax index measures the rate at which a fabric absorbs heat from your skin upon first contact, in watts per square centimeter. The higher the value, the more immediate the cooling sensation. Cotton scores around 0.10, while the market benchmark is 0.15. JadeCool™ reaches 0.18 and TechCool™ 0.22. PolyCool™ is not subject to this measurement, as its effectiveness is based on duration rather than initial contact.
- The number of activation steps: one for TechCool™, two for PhaseCool™, and four for JadeCool™ and PolyCool™. In practice, this detail often determines how the garment is actually used.
- Sun protection: UV-protective fabrics filter out more than 98% of UVA and UVB rays on areas covered by the fabric, whether dry or wet.
- Reactivation: All our technologies can be reactivated an infinite number of times. For PhaseCool™, reactivation requires cooling the fabric below its melting point.

Master the use and care of your G-Heat cooling garments
“The most common ‘failure’ isn’t a failure at all—it’s a garment that hasn’t been properly activated. A JadeCool™ towel that hasn’t been shaken out will never reach its full effectiveness, and a PolyCool™ vest wrung out by twisting loses part of its cooling capacity permanently. Two simple steps, and everything changes.”
Romane Benderradji, G-Heat Technical Team
Optimize cooling duration based on the technology
Each product line has its own sequence, and the order matters.
JadeCool™ requires four steps: soak, wring out, shake, put on. Shaking is the step people tend to forget, and it’s the one that triggers the cooling effect in fifteen seconds. PolyCool™ follows an immersion process: soak until saturated, gently wring out, remove excess water, put on. The effect kicks in within five minutes and lasts two to six hours.
TechCool™ requires no preparation: just put it on, and the fabric activates as soon as you start sweating. PhaseCool™ takes just two steps: check that the material is in a solid state, then put it on. The melting process starts automatically once the material exceeds its threshold temperature and lasts two to four hours.
Proper Care for Your Cooling Clothing
Three rules are all you need to maintain performance over time.
- Never wring out a PolyCool™ product. The super-absorbent polymer is damaged by forceful wringing, and the loss of capacity is irreversible. Squeeze, don’t twist.
- Wash in cold water or at 30 °C maximum; do not tumble dry. The heat from the dryer degrades the active structures, whether they’re crystals or the fabric weave.
- Dry flat, in the shade. Drying a product that’s still saturated in direct sunlight accelerates material wear without providing any benefit.
When properly cared for, these technologies can be reactivated indefinitely. That’s what sets a cooling garment apart from a single-use accessory.
Conclusion: It’s up to you to find the ideal cooling garment
There’s no such thing as the “best” cooling garment—there’s only the one that’s right for you. Ask yourself the first question in the buying guide—the one about water—and two technologies are immediately ruled out. Factor in exposure time, and only one remains.
Our lineup covers all four scenarios, from the T-shirt that activates on its own during exercise to the vest that lasts through a full day of stationary work. If you’re still unsure, start with the T-shirt that best suits your primary use and complement it with an accessory: this combination delivers the best results over a full day.
Whatever the weather. G-Heat, in all weather conditions.
Frequently Asked Questions About Cooling Clothing (FAQ)
What are the best clothes for dealing with the heat?
The best clothes for dealing with the heat are those whose technology matches your situation. For physical exertion, a TechCool™ T-shirt that activates with sweat and keeps your skin dry. For prolonged, stationary exposure, a water-filled PolyCool™ product, which lasts two to six hours. For an immediate cooling effect, a JadeCool™ towel or neck wrap.
What clothing is recommended for combating a heat wave?
During a heat wave, combine a garment that works continuously with a cooling accessory for on-demand relief. A UV-protective T-shirt shields against radiation and keeps you cool all day long, while a cooling towel can lower the perceived temperature in seconds on the back of the neck, wrists, or forehead. Vulnerable individuals and children should prioritize covering their heads and the backs of their necks.
What types of clothing provide cooling relief?
Cooling clothing uses active textile technology, unlike simply breathable clothing, which merely wicks away moisture. At G-Heat, there are four product lines: TechCool™, featuring a three-layer weave; JadeCool™, incorporating jade microcrystals; PolyCool™, using a super-absorbent polymer; and PhaseCool™, made from a phase-change material. T-shirts, shorts, caps, hats, towels, neck gaiters, headbands, wristbands, and vests are all available in one of these technologies.
What kind of fabric should you wear when it’s very hot?
Avoid cotton, which has a Qmax rating of around 0.10 and traps moisture against the skin without wicking it away. Opt for a technical fabric designed for thermal management: a multi-layered weave that wicks away sweat, a fiber infused with jade microcrystals, or a polymer capable of storing water and slowly releasing it. The difference in how it feels against your skin is immediately noticeable.
Does cooling clothing work without water?
Yes, for two of our four technologies. TechCool™ works solely with your sweat and keeps the garment dry. PhaseCool™ requires no moisture and maintains a controlled temperature for two to four hours. JadeCool™ and PolyCool™, on the other hand, need to be wet to activate.
How long does the cooling effect of a garment last?
It depends on the technology. TechCool™ works continuously as long as you’re wearing the garment and your body is sweating. PolyCool™ lasts two to six hours depending on how much water it absorbs, with the cooling effect kicking in within five minutes. PhaseCool™ maintains its cooling effect for two to four hours before needing to be recharged. JadeCool™ starts working in as little as fifteen seconds; its effect lasts for a shorter period but can be reactivated in just a few seconds.
Do cooling garments provide sun protection?
The UV-protective fabrics in the line filter out more than 98% of UVA and UVB rays on the areas covered by the fabric, whether dry or wet. This protection works independently of the cooling effect. Please note, however, that it only covers the areas actually covered by the garment and does not replace protection for the face and exposed areas.
Can cooling clothing be machine-washed?
Yes, in cold water or at a maximum of 30 °C, without using a dryer. The most important precaution concerns PolyCool™ products: never wring them out, as this will permanently damage the super-absorbent polymer. Gently squeeze out excess water and lay them flat to dry in the shade.
