NEW - JUST ARRIVED

New heated thin mid-layer garment designed from the ground up, using specially designed textiles and an enhanced heating system.

This new Heated Bodywarmer has been designed to deliver maximum comfort and superior heating efficiency - featuring UltraFlex technology. This B601RP bodywarmer features a much thinner material structure than the alternative soft-shell V501RP heated vest and B501WRP ladies heated bodywarmer - being designed to fit between the wearer's base-layer and their outer motorcycle jacket when there is not a lot of space to accommodate a mid-layer heated garment. The unique UltraFlex material also provides generous elastic 4-way stretch, moulding the garment to the wearer’s body contours for a snug fit, without restricting movement.

UltraFlex 4 way stretch

Keis developed UltraFlex specifically for motorcycle mid-layers, so that riders can enjoy riding safely in colder environments. The fabric is lightweight, breathable, and wicks away moisture, keeping riders comfortable and dry, while the Keis heating panels deliver warmth to strategically positioned areas of the body.

The unisex Keis UltraFlex Heated Bodywarmer delivers 41W (3.4A) of power to heat panels in the chest, back, and collar.

Connect & power

It is recommended that you power the B601RP UltraFlex Heated Bodywarmer from a vehicle battery, using the supplied Keis Power Lead.

While this heated bodywarmer can technically be powered by a Keis Portable Battery Pack, we believe that this may not be very practical. As the heated bodywarmer draws 3.4Amps 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 bodywarmer be powered from a vehicle battery connection.

This heated bodywarmer 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 are also able to power this heated garment using a optional cigarette lighter/DIN power lead.
