heating element in sleeping bag

The sleeping bag has a carbon heating element in the foot area.

If you are exhausted, sick or already cold, your body will have difficulty or even not be able to warm itself up.

A sleeping bag doesn't generate heat, but merely reflects body heat. To keep the sleeping bag warm in such cases, you can connect a standard power bank to the USB port in the inner pocket. This will heat the sleeping bag. The heating lasts for 10 to 20 minutes , after which the sleeping bag stores the temperature.

The heating element is limited to 102.2 degrees Fahrenheit because this is the optimal temperature: the feet do not start to sweat and do not get cold again due to the moisture.
