Techcool

Put them on. Move. That’s it. TechCool™ technology is the simplest thermal regulation system on the market: a technical fabric that manages heat as soon as you start sweating—no water, no preparation required.

This collection features sports apparel and accessories equipped with TechCool™, G-Heat’s passive cooling fiber. Each product works dry, continuously, as long as you’re moving.

The TechCool™ line covers tops, bottoms, and headwear:

• Tops: the men’s cooling sports T-shirt, part of the TechCool™ cooling T-shirt collection.
• B BottomsB : the men’s cooling sports shorts and the women’s cooling sports shorts, part of the cooling shorts line.
• Headwear: the lightweight, unisex cooling sports headband, which wicks sweat away from your forehead.

TechCool™ is just one of G-Heat’s four cooling technologies. For static activities or extreme heat, Jadecool technology and its jade crystals take over. This collection, however, is designed for active sports.

It’s the fabric that does the work, not an accessory. That’s what sets TechCool™ apart from all other thermoregulation systems.

The TechCool™ fiber is based on a multi-layered technical weave. This weave absorbs sweat and promotes its rapid evaporation. As it evaporates, the moisture carries body heat away. The result: an immediate cooling sensation and skin that stays dry.

The key difference lies in how it’s activated. Traditional cooling technologies require some effort:

• Wet-activated textiles (such as JadeCool™ fiber with its jade crystals): you have to wet, wring out, and shake them to activate the cooling effect.
• Phase-change inserts: you have to put the packs in the freezer before you head out.
• TechCool™: nothing. The fabric activates on its own, using air and your own sweat.

No water source, no fridge, no gel. Passive, dry cooling that can be reused indefinitely, wherever you go.

“We designed TechCool™ for athletes who don’t have time to soak their clothes. You put it on, you run, and the fabric does the work as long as you’re moving. It’s the most direct cooling we know how to produce.” — Édouard Castaignet, founder of G-Heat

It’s 35 °C outside. You go out anyway. That’s exactly what TechCool™ promises.

Cooling apparel isn’t designed to “cool your body down”; it helps wick away the heat you generate. The TechCool™ fiber accelerates this process to keep you within your comfort zone. This results in three concrete benefits:

• Consistency: Finish your outing, workout, or day without suffering from the heat that brings you to a halt.
• Safety: Keep a clear head and steady legs, because overheating impairs alertness and performance.
• Freedom: No longer have to accept the weather as inevitable, and turn a heatwave into just another factor to consider.

All without a battery, without recharging, without any constraints. You stay dry and comfortable from start to finish. The rest is just physics.

The right choice depends on your activity and the area you want to protect. There’s no need to overdo it: TechCool™ is designed to be worn piece by piece, depending on the level of exertion.

Three criteria are all you need to make a decision:

1. The body area: the torso with the T-shirt, the legs with the shorts, and the head with the headband. You can combine all three for a complete outfit.
2. The intensity of the activity: for intense sports, opt for a slim fit and lightweight fabric. For everyday wear, comfort is key.
3. Sun exposure: TechCool™ T-shirts and shorts feature built-in UV protection, which is useful for long outings in direct sunlight.

In terms of technical features, the TechCool™ line prioritizes lightness:

• The sports T-shirt: 120 g on the back, slim fit, mesh panels under the arms, UPF 50+ protection.
• The sports shorts: 150 g, stretch fabric, slim fit that moves with every stride.
• The sports headband: 17 g on the forehead, unisex, designed to absorb sweat without slipping.

To go beyond TechCool™, G-Heat’s cooling apparel covers all other technologies and areas of the body.

Right here, at the source. G-Heat has been designing, testing, and validating its thermoregulation systems in the field since 2017.

“Our customers come back for one main reason: it works from day one, without a user manual. We’re always available to help you choose the right product for your business.” — Romane Benderradji, G-Heat team

As soon as the temperature rises and you want to keep moving. TechCool™ is designed for action, not for napping in the shade.

Here are the times when this fabric makes all the difference:

1. Summer sports: running, cycling, trail running, CrossFit. You don’t cancel your workout at 35 °C—you prepare for it.
2. Family outings: walks, markets, sightseeing, a day at the beach with the kids—without the heat ruining everything.
3. Active commutes: biking to work, hopping from one place to another around town under the sun.
4. Outdoor work: Outdoor professionals exposed to the heat find a dry, lightweight ally in this T-shirt and shorts.

What all these uses have in common: no preparation needed. You put the garment on in the morning, forget about it, and it does its job all day long.

The process can be summed up in one word: put it on. Where other technologies require an instruction manual, TechCool™ doesn’t need one.

In practice:

• No water: no need to soak the garment before heading out.
• No waiting: the fiber activates as soon as your body starts sweating.
• No limits: the cooling effect renews itself as long as you’re moving, session after session.

The cooling sensation kicks in within the first few minutes of exercise and then lasts naturally. No recharging, no freezer, no technical steps. It’s the very definition of dry activation, usable by everyone, from marathon runners to parents in a hurry

Simple care preserves the effectiveness of the technical fabric over time. TechCool™ fiber can be washed like any other sportswear, without any special precautions.

Best practices:

• Washing: Preferably by hand, or in the washing machine at a maximum of 30 °C, using a mild detergent and no fabric softener.
• S: Air-dry; never use a dryer, as it damages the technical fibers.
• Storage: Always store in a dry place. Storing a garment while it’s still damp can lead to mold.

Do not use bleach, iron, or dry clean. When properly cared for, your TechCool™ garment will stay cool wash after wash, season after season.
