Nevercold Tundra

Nevercold Tundra NEVERCOLD Tundra is an effective and versatile high-neck thermal vest. Its four bulky but thin heating elements distribute heat evenly across the chest and back. The large heating element on the upper back measures no less than 20 x 22 cm, while the heating elements on the chest and lower back measure 20 x 11.5 cm. The vest has a multi-layer construction to ensure optimum performance in all conditions. The outer layer of the vest is a polyester microfleece fabric with a windproof membrane underneath, while the inner layer is a mesh lining. The thin and discreet red microfibre heating elements are positioned between the mesh lining and the tulle membrane, as close to the wearer's body as possible to minimise heat loss. The Tundra thermal vest is powered by a small but powerful lithium-ion battery, which has its own discreet place in the vest's battery pocket. The battery is charged using any charger with a USB A or USB C output (e.g. mobile phone charger) and the charging cable supplied with the vest. Charging the battery consumes only about 0.05 kWh of energy, so even at high electricity prices (50 c/kWh) the cost of charging is only about two to three cents. The Tundra has two battery pockets. By purchasing an extra battery, you can use two batteries at the same time, doubling the life of the vest. The Tundra thermal vest has three levels of temperature control. The heating intensity is selected by a push button on the left chest of the vest. The colour of the button light indicates the selected heating intensity. At full power, the heating elements have a temperature of 52 °C and a battery life of approximately 2.5 hours. At the lowest power level, the heating elements are heated to 38 °C and the battery life is approximately 8 hours. If you use two batteries at the same time, the battery life is about 5 hours at full power and about 16 hours at minimum power. Heating can be switched off completely by push-button when not required. The Tundra thermal vest's heating properties are at their best when worn directly over a layer of underwear. In this case, the heating elements are as close to the body as possible. The vest should also be sized to provide a snug fit so that there is not too large a layer of air between the body and the vest. If the vest is too loose, it will reduce the sensation of warmth experienced by the wearer. The Tundra thermal vest can also be used to dry a wet undershirt when sweating, without having to take it off. About half an hour of heating at full power is usually enough to dry the shirt.
