Keis B601RP UltraFlex

Keis B601RP UltraFlex Heated Vest – ultra-thin, flexible & powerful warmth for the upper body

The Keis B601RP UltraFlex Heated Vest is a strong, slim, and flexible heated vest. It is the missing link between the especially warm Keis jackets and the outdoor vests. Essentially, it is a sleeveless heated jacket – light, slim, and perfect for those who only want to heat the torso, back, and neck. The heating elements on the chest, back, and collar are identical to those of the heated jacket J601RP.

Made from the same flexible and lightweight material as the J601RP, the vest offers full heating performance with maximum freedom of movement. Thanks to the ultra-thin fit, it easily fits under tight leather and textile jackets.

With 41 W heating power and targeted heating zones on the chest, back, and collar, it provides intense warmth while remaining so thin and flexible that it can also be worn easily under tight motorcycle jackets – ideal for roadster or sportbike.
