How It Works

Important Information

What is Far-Infrared Rays?

Far-infrared rays are part of the sunlight spectrum which is invisible to the naked eye. The complete spectrum of sunlight consists of visible and invisible rays. The visible rays are red, orange, yellow, and green, indigo, blue and violet in colours and the wavelength ranges from 0.4 micron to 0.75 micron. The invisible rays are Ultra Violet, X-rays, Gamma, Cosmic, Microwave, Long Wave, Electrical Wave and Infrared. The wavelength of Infrared is 0.75 to 1,000 micron, and it consists of Near, Medium and Far Infrared Rays (FIR). We live in an environment of FIR waves and our body receives and radiates them. Among the energy spectrum coming from the sun, the FIR waves are the safest and the most beneficial electromagnetic energy sources available; especially it is when the resonant frequency id from 4 to 14 microns called “Bio-Genetic Rays ". The Bio-Genetic Rays causes the water molecules in the body to vibrate and then it cause heat reaction through resonant absorption; and the heat causes the temperature under skin to increase it. Thus, caused expansion of capillaries to promote blood circulation and eliminate obstacles that hinder metabolism; and the tissues get activated to result in the formation of enzyme. In the blood stream, it is able to neutralize blood toxicity and smooth the walls of arteries, capillaries and veins. It could also help enhance the cancer cells back to normal healthy cells. That is why the Bio-Genetic Rays is so amazing.

The effect of Far-infrared Rays on our human body

FIR causes resonance with water molecules. It ionizes and activates water molecules in our cells and blood thus improving our blood circulation and health condition, and it improves oxygen level in our body. It can be absorbed and produce warmth and harmonize with the natural life force released by the human body to enhance resonance absorption; the ability to penetrate deep into the human body. Therefore, it can be applied in many products, especially the clothes that are not only light but also thin and suitable for sports, spectators or exercise, such as the clothes for OH&S, sports, hiking, Medical, mountain climbing, skiing, and scuba diving, etc. and many, many more.

The applications for these products and the Biothermal heated cell is only limited by your imagination.


Road test: Alpenheat AJ4B fire fleece


Alpenheat AJ4B fire fleece Vest

How does it work?
It looks like a regular sleeveless fleece, but built into the fabric on the back is a thin, flexible heating element, the size of an A4 sheet of paper, which connects via a wire to a palm-sized battery/control-unit in the front right pocket.

So isn't the garment kind of lumpy?
Not at all - the integration is seamless. You can barely feel the shape of the heating element, and you can't even see any bulges from the outside.

How toasty is it?
The control unit offers five heat settings: the warmest is like having a hot-water bottle between your shoulder blades. If you wear the fleece (which is machine-washable) under a top layer, your whole upper body hums with heat.

How long does it last? Each recharge of the lithium battery gives you between 2.5 and 7.5 hours of use, Alpenheat says.

So what's it for?
Heated clothing is widely used by motorcyclists in cold climates, but its potential applications are much wider. For an elderly person in a draughty house, say, or for skiers. Or even for spectators at a footy game - and the best thing is, your mates won't call you a wuss ... because they'll never know.

This Is How It Works

1. Led Torch Flashlight

2. on Switch / Increase temp. Level

3. Heat level indicator

4. off Switch / Decrease temp. Level

3. Heat level indicator

5. Power plug inlet and Plug fixing to vest 

Press the ON/OFF key for 3 seconds, the number 2 on the temperature controller will be displayed. This is the default setting when switching the battery heat on.

The temperature can be increased / decreased by pressing the up / down button.

Hold down the On/Off key for 3 seconds to switch off the battery pack.

It takes approximately 5 minutes to feel the heat.

The approximate values of the heat levels are:

1 = 40degreesC, 2 = 45DegreesC, 3 = 50DegreesC, 4 = 55DegreesC, 5 = 60DegreesC

The heating element will maintain a temperature range from 40DegCelcius to 60DegCelcius.


The battery will keep on working for up to 7 hours before it needs to be recharged.

The battery will show an indicator from 1 - 9 (flashing) to show the status of the battery charge and at what level of charge the battery has left to operate the vest.
