Imagine being in the sun on a cold day; the warmth seems to penetrate your body. The air temperature may be zero, but you remain warm at least until the sun goes in. That’s Far Infrared. Compare that to being in a warm room where it’s the air that keeps you warm. Keis technology is designed to deliver Far Infrared reliably, effectively and as efficiently as possible.

Fine, yet incredibly rugged, micro carbon and alloy fibre heating elements are strategically placed within the garments, and provide a lightweight, flexible Far Infrared heat source with a long service life, offering extreme comfort.

Different garments are designed to work at different temperatures. It’s also important to bear in mind that our Dual Powered body warmers have been specially designed to maintain the correct balance between the heat generated by the body and heat loss to the environment. They are not designed to ‘feel’ hot. Our High Powered garments, on the other hand, will almost always benefit from the use of the optional controller to provide optimum comfort.

Most Keis garments can be powered both from a 12V source, such as a vehicle battery, or from 12V Li-Ion Keis battery packs. We call these our ‘Dual Power’ products. Dual Powered products have the advantage of being used anywhere – and by managing multiple battery packs it’s possible to remain warm for long periods in any situation.

Most larger motorcycles will power any number of garments – for example, jackets, trousers and gloves – without difficulty. However, for smaller bikes running a number of garments you should take the advice of your dealer or contact us directly, providing details of the motorcycle and the garments involved.
