Thermo Cell Technology

Thermo Cell is equipped with a multilayer insulation cover that reflects the heat on the inside and shields from the cold and wind from the outside. By its design, the Thermo Cell closes tightly to the body and a thin mesh membrane permits maximum body heat to pass through. Used in this way the body heat feeds the Thermo Cell with thermal energy. Smart!

Thermo Cell encapsulates heat from physical activity in an insulating air pocket that protects the tube and bite valve from freezing even in the most extreme winter conditions. Therefore, we have chosen to provide both shoulder straps on the NORDIC, HAJKER, POW and BRANT backpacks with Thermo Cell so that you get the option of choosing which side you want to have the tube in tube, or having tubes on both sides (double hydration bladders). Or optional, why not store gels and bars that you easily reach on-the-go in the pocket you don't use.
