The Scram Knee Guards from REV'IT! pack CE Level 2 impact protection into a tough, compression-style knee sleeve. Beneath the surface of the Scram Guards lies a REV'IT! Seeflex impact protector - the highest performance impact protector found in the REV'IT! line. This low profile, perforated protector covers the knee and extends downward into the boot, covering the entire lower leg. The PWR|Stretch mesh chassis is tough and allows airflow through the open-structured Seeflex guard. Neoprene inserts add some stretch, and the entire unit is kept in place by adjustment straps at the top and bottom.
