Thermo Underwear is our latest development, a heatable underwear that fits perfectly under your leisure, sports and everyday clothes. Since the underwear is worn directly on the body, the heating elements are particularly effective and offer you optimum protection from the cold. 

The underware is made of a skin-friendly material and can of course be washed. The material of the underpants is elastic and fits close to the skin. Therefore it can also be used for sports such as skiing, hiking, walking, ice skating, motorcycling, sailing, horse riding, gliding, hunting, etc.

The heating elements of the undershirt are located in the back and kidney area and radiate over the entire back. The heating elements of the warmers are located in the knee and thigh area and radiate into the entire leg area.  

The batteries of the undershirt are fixed in two pockets on the side of your upper body in the area of the arm bends, so that you will not feel and notice the batteries at all. The power button is located at the end of the left sleeve, so you can operate it even when wearing a shirt, sweater or jacket over it. 
The batteries of the warmers are stored in a battery bag with a separate extension strap so that they can also be stowed in the inside or outside pockets of a jacket. 
Depending on your wishes, 3 possible stowage and carrying options are possible

•    directly at the waistband on the left side
•    with the extension strap (included) in the inside pocket of the jacket
•    with the extension cord (included) in the jacket pocket outside

Thermo Underwear has 3 different temperature levels with 34 degrees C, 39 degrees C and 44 degrees C.

The heat lasts between 2 and 5 hours depending on the temperature level, but this doesn't mean that you freeze afterwards. The batteries can be easily replaced. The replacement batteries are extremely light and weigh only 59 grams each. Thus they are light enough to always have a second pair of batteries with you.

The supplied batteries are high-performance lithium polymer batteries that have no memory effect and can be recharged up to 500 times. In addition, a battery weighs just 59 grams each, so you won't feel it on your body.

THERMO UNDERWEAR comes with two rechargeable batteries and a charger, the warmers are also supplied with a detachable battery bag and a separate extension strap.
