CARBON HEATING ELEMENT
Spare part for Grüezi bag® hybrid mummy sleeping bags
The carbon heating element is the first heating element for a sleeping bag in the world that can be connected to a standard power bank using a USB interface. Once connected, the washable heating element warms your feet.
The heating output is limited to approx. 40 °C so that your feet don't start to sweat and become damp, which makes it cold again. The heating part itself was integrated into the foot part: Here the heat is distributed well from bottom to top and the heat source is far enough away from the body to be able to sleep more peacefully.
Can be ordered as a spare part for all Grüezi bag® hybrid mummy sleeping bags. The “Biopod Down Hybrid Ice Alpine” can be retrofitted with the heating element.
