    Due to the elasticated side panels you may find you need to order the chest size smaller for a snug fit. A snug fit provides the most efficient transfer of heat from the heated jacket, through your required under layer (e.g. long sleeved t-shirt), to your upper body.

        Connect & power

        It is recommended that you power the J505RP Extreme Heated Jacket from a vehicle battery, using the supplied Keis Power Lead.

        While this heated jacket can technically be powered by a Keis Portable Battery Pack, we believe that this may not be very practical. As the heated jacket draws 6.5Amps of current to heat the many different Micro Carbon Fibre heating elements, a portable battery is not recommended to power this garment. It is advised that this heated jacket be powered from a vehicle battery connection.

        This heated jacket can also be powered via the Keis Cigarette Lighter/DIN Power Supply Lead (available as an optional accessory).

        Connecting the supplied motorcycle power lead is quick and easy.

        SPECIAL NOTE - You are unable to power this heated garment using a cigarette lighter/DIN power lead on a BMW motorcycle, due to the 5Amp limit to their DIN power socket (the jacket draws 6.5Amps).

        Powering your Keis Extreme Heated Jacket from the supplied motorcycle power lead.

        Connecting and using your Keis Power Controller with your Keis Extreme Heated Jacket.

        Connecting your Keis Heated Jacket to Keis Extreme Heated Motorcycle Gloves.
