Knee Guard ReaFlex UltraLite EXT delivers full-length, ultra-light protection for long rides
What Our Gearhead® Experts Are Saying:
"I grab the UltraLite EXT when I want shin protection without feeling weighted down. The high-rise sock design keeps everything stable, and the ReaFlex gel stays flexible while pedaling. For long days or warm weather riding, it’s one of the most comfortable guards I’ve used."
We appreciate knee protection that feels natural on long, varied rides, and the Knee Guard ReaFlex UltraLite EXT from Leatt brings that blend of comfort and coverage to all-day terrain. The full-length design supports smooth pedaling, stays breathable in warm conditions, and adds the reassurance of shin protection when technical features or pedal strikes come into play.
ReaFlex impact gel offers soft, flexible movement while stiffening on impact to provide certified protection where it counts. A hard shin plate adds coverage for pedal contact, and strategic padding at the sides and upper thigh enhances safety in tight, unpredictable lines. The extended high-rise sock supports the leg without squeezing the calf, keeping the guard secure throughout long climbs and committed descents. With perforated materials and moisture-wicking fabrics, airflow remains strong even on hot days, helping us stay comfortable and focused.
