STAY IN MOTION, WHATEVER THE WEATHER

We are a French brand specialising in thermoregulation. At G-Heat, we design thermal clothing: heated for the cold, cooling for the heat, for trail running, running, skiing and hiking.

The principle is the same both ways: helping the body keep the right temperature for the length of an outing. Fingers that still respond at -6°C at the top of a mountain pass. A pace that holds at 32°C on a trail with no shade.

For ten years, it has been our only focus.

In the Alps, winter 2016. One of our two founders has been skiing since childhood. He also has Raynaud's syndrome. After a few runs, the feeling leaves his fingers, then his dexterity goes too. Yet his legs would have lasted the whole day.

With his partner, he tries what's out there. It's either too thick to ski in, or it gives out before noon. So in 2017, they decide to design it themselves. The first pieces are heated. They spend their first winter on the slopes, worn by skiers who report every flaw.

Cold is only half the problem. On a trail in the middle of summer, it's the heat that sends you home early. In 2021, the cooling range arrives, and our work takes on its true name: thermoregulation. Helping the body all year round, whatever the conditions.

Today, there are 18 of us in Paris. We test the pieces ourselves, and we answer when a customer writes to us.

The body keeps its temperature at around 37°C. This is thermoregulation.

In cold weather, it constricts the blood vessels in the extremities to protect the upper body: hands and feet are the first to get cold. 

In hot weather, it sweats. Sweat cools the skin as it evaporates, but in hot, humid air it evaporates poorly, and heat builds up.

Effort, wind and duration push this system to its limit. That is where our work begins: helping the body retain its heat when it loses too much, and limiting overheating when it produces too much. Cold and heat are part of the same job.
