Heated clothing keeps your body warm even when the temperature drops. But how does that actually work?
This is how heated clothing works
Heated clothing works differently than ordinary thermal clothing.Instead of just insulating, it actively adds heat. Exactly where your body needs it most.This is done via ultra-thin thermal conductors, controlled by a smart chip and powered by a compact, rechargeable battery.
Depending on the garment, the heating zones are located in strategic locations:
- on shirts and jackets on the chest, back or lower back,
- on pants around the lower back, knees, abdomen or thighs.
Heat is distributed evenly, keeping your entire body comfortably warm, even when sitting still or when the wind cuts.
The heat system
At the heart of each heated garment are thin, flexible heating wires made of carbon. These run through the fabric in carefully chosen places – for example, along the back, chest, shoulders, thighs or knees.
- Carbon is extremely strong, light and conducts heat in a natural, even manner.
- The threads are so finely woven into the fabric that you do not feel them while wearing.
- A smart chip constantly monitors the temperature and regulates the battery’s power supply.
- This keeps the heat stable, with no spikes or cold swings, and the system automatically switches back if it threatens to get too hot.
Operation is simple
With the push of a button you activate the heater. Quick and easy.
Rechargeable battery
Up to 8 hours of pleasant heat with a powerful 7.4V rechargeable battery.
Heat modes
HeatPerformance®’s heated clothing has three heat settings:
- High setting – to warm up quickly after exposure to cold.
- Medium setting – for prolonged warmth during outdoor activities.
- Low setting – ideal for indoor or mild conditions.
In just 5 to 10 minutes, the cold is gone, after which you can switch to a lower setting to maintain a comfortable temperature.
The Battery
Each garment has its own battery compartment where you store the rechargeable lithium battery.
The battery is connected to the heat system via a small plug, but you won’t feel a thing while wearing it.
power
The batteries are light, powerful and resistant to low temperatures.
Depending on the battery content, you will enjoy between 3 and 9 hours of heat
After use, fully charge the battery in about four hours with the included charger.
Safe & Energy Efficient
Safety and efficiency are at the heart of every design:
- Overheating protection: automatically switches back if the temperature rises too high.
- Power management: the chip precisely controls power distribution so that no energy is lost.
- Weatherproof design: the textile layers and connectors are resistant to moisture, wind and cold.
So you can wear your heated clothing with confidence – during work, sports or relaxation.
How long will it stay Warm?
Battery life depends on three factors:
- the selected heat setting,
- the outside temperature,
- and the type of clothing.
A thicker pant or jacket retains heat longer than a thin baselayer shirt.
On average, you can expect 3 to 8 hours of constant warmth, depending on conditions.
Want to stay out longer? Then you can bring a second pair of batteries for the road.
Use and maintenance
- Don’t switch on the clothing until you are wearing it – that way you won’t lose energy.
- Only wash the garment by hand or on a gentle program after removing the batteries. Always use the provided laundry bag.
- Let the connections dry thoroughly before reconnecting the batteries.
- That way, your heated clothing will stay in top condition and last for seasons.
