Cooling T-shirts for men

The G-Heat cooling T-shirt for men lowers the perceived temperature to 15 °C in 15 seconds, thanks to JadeCool™ technology and built-in UPF 50+ UV protection. Washable and infinitely reactivatable, without any chemicals.

The men’s collection is available in three styles:

• Short-Sleeve UV Protection: 5 colors (Black, Blue, White, Green, Orange), regular fit, 173 g. The versatile everyday choice.
• Men’s Long-Sleeve UV Protection: 3 colors (Black, Orange, White), regular fit, 216 g. Covers the forearms, ideal for bright sunlight and outdoor work.
• Unisex Long-Sleeve UV Protection: Gray, regular fit, 197 g. The more understated unisex version for long workouts and workwear.

Sizes available from XS to 4XL on all styles. All offer the cooling sensation of 15 °C, UPF 50+ protection, and immediate activation when wet.

Staying cool isn’t just about comfort—it’s essential for performance. When temperatures rise above 30 °C, your body uses more energy to regulate its temperature than to move forward. Your legs slow down, you feel lightheaded, and your concentration drops.

The men’s cooling T-shirt steps in when your body’s natural temperature regulation fails. The principle is simple: polyester fibers embedded with jade microcrystals conduct body heat outward, and the evaporation of water retained in the fabric prolongs the cooling sensation for several hours.

“We don’t cool the body down—we help it dissipate heat faster than you produce it. That’s what true thermoregulation is all about. ” — Gwenaël Fournet, Technical Manager at G-Heat

Three promises kept every time you put it on:

• Endurance: Finish your bike ride, hike, or day on the job site without hitting a wall halfway through.
• Safety: Stay alert and reduce the risk of heatstroke in high temperatures.
• Freedom: Stop enduring summer as an inevitability; head out fully equipped and keep moving forward.

Added to this is UPF 50+ UV protection, which blocks more than 98% of the sun’s rays on covered areas. A technical layer that replaces sunscreen on the torso, shoulders, and—in the long-sleeved version—the forearms

Three criteria are all you need: activity × environment × body area to cover. The rest is just a matter of color.

Choose the model based on your main use:

• Summer sports and leisure (running, cycling, hiking, outdoor activities): the short-sleeve UV-protective T-shirt. Lightweight (173 g), regular fit, provides immediate cooling as soon as you sweat or when reactivated with water.
• Outdoor work and prolonged periods of intense heat (construction, gardening, tourism): the men’s long-sleeve UV-protective T-shirt. Your forearms are protected from the sun, and the cooling zone covers your entire torso and arms.
• Versatile use and understated workwear: the unisex long-sleeve version in gray. The same protection, a more discreet design.

When it comes to colors, the choice depends on your exposure and the situation:

• Light colors (White, Blue): reflect the sun’s rays, more effective during prolonged exposure.
• Bright colors (Orange, Green): increased visibility for cycling or working roadside.
• Subdued colors (Black, Gray): for everyday wear, the office, or activities where discretion matters.

As for sizing, please note that these models run slightly small. If you’re between sizes, choose the larger one. Sizes range from XS to 4XL, so there’s a fit for every body type.

“Our job isn’t just to offer you a T-shirt. It’s to ensure that, even at 35 °C, you can finish what you started.” — Édouard Castaignet, founder of G-Heat

As soon as the temperature rises above 25 °C, it’s time to break out your cooling T-shirt. Above 30 °C, it becomes an essential tool for maintaining your activity.

Five real-life scenarios, ranked by frequency of use:

1. Sports and outdoor activities: a Sunday morning run at 8 a.m., road biking in the blazing sun, trail running in the Calanques, or a long hike. The short-sleeved UV-protective T-shirt is ideal for these activities.
2. Family and everyday life: a day at the beach, a stroll through town, the park with the kids, a weekend camping. It stays cool without a battery or cooler—just a water source to reactivate it.
3. Motorcycling and urban cycling: worn under a motorcycle jacket to create a cool microclimate. Quick reactivation when stopped, without having to take off your gear.
4. Health and seniors: to stay active during heat waves without overheating. Short outings, walking, gardening.
5. Outdoor work and construction: construction sites, landscaping, deliveries. The long-sleeved version protects your forearms from the sun while keeping your torso cool.

The product also works in overheated indoor spaces: open-plan offices without air conditioning, workshops, and commercial kitchens. Anywhere the ambient heat exceeds your tolerance, it takes over.

Three steps. Not one more.

All T-shirts in the collection use JadeCool™ technology. It activates with water in less than a minute:

1. Soak the T-shirt in water until it’s completely saturated. Cold, lukewarm, or room-temperature water—it doesn’t matter.
2. Wring it out firmly. The fabric should be damp, not dripping wet.
3. Shake the T-shirt with a sharp motion to activate the jade microcrystals through airflow.
4. Put it on: You’ll feel the cooling effect within seconds, with a surface temperature of 15 °C.

The effect lasts for several hours depending on the ambient temperature and humidity. As soon as the fabric dries out, reactivate it: a quick dip in a water fountain, under a faucet, or even in a stream is enough. There’s no limit to the number of uses, and the effectiveness doesn’t diminish over time.

Practical tip: In hot, dry weather (southern France, summer in direct sunlight), plan to reactivate the shirt every 1 to 2 hours. In humid weather, the cooling effect lasts longer but the sensation is less pronounced. It’s basic physics: evaporation accelerates cooling when the air is dry.

The cooling T-shirt can be washed using standard care instructions, provided you follow a few simple rules to preserve the fibers and jade microcrystals.

Care Instructions:

• Hand washing recommended, or machine wash at a maximum of 30 °C with a gentle spin cycle.
• Mild detergent without fabric softener: Fabric softener clogs the technical fibers and reduces the cooling effect.
• Air dry only. Do not tumble dry.
• Do not iron, do not use bleach, and do not dry clean.
• Never store the T-shirt while damp: this may cause mold to grow on the fibers.

Composition: main fabric 100% polyester. On unisex long-sleeve models, the side panels contain 80% polyamide and 20% elastane for stretch.

When properly cared for, the cooling T-shirt retains its effectiveness season after season. No expiration date, no limit on the number of washes: the cooling effect can be activated indefinitely.
