Directional Flex SpaceHeater Liner – The all-new SpaceHeater liner is the result of a two year development process with the K2 Alliance. For years they have tolerated cold feet while riding and decided to put an end to the chills. By building in their SpaceHeater silver reflective material around the toes and instep, your natural body heat reflects back and stays in the liner. At the same time cold coming in from the shell is reflected back and stays out. A simple solution to an age-old problem.
