Our latest jacket

J601 ULTRAFLEX

The latest KEIS jacket, the ULTRAFLEX is a thinner, more lightweight version of the J505, using Micro Carbon and Far Infrared tech across the chest, back and collar. With an integrated battery pocket, the ULTRAFLEX can now be used with the 5000mAh KEIS battery or powered directly by your bike. With a Microsuede lining, the ULTRAFLEX remains hot, but breathable, and a lowered back, reducing risk of the jacket riding up during your journeys.
