When it comes to riding on cool spring and fall days, we like to add layers that keep us warm without making us overheat. With the Spring/Fall EVO Knee Warmer, Assos brings us the perfect balance between too warm and too cold. The leg warmer is great for cool summer mornings, cold fall days, and spring days that just won't warm up. Its compressive construction provides a bulk-free layer that won't get in the way of your pedal stroke.
