Minimalistic, comfortable, ergonomic fit and uncompromised CE certified impact protection. The Airflex knee guard Pro is an engineering masterpiece! The lightweight construction, single sizing, and silicone grip panels made it possible to delete the thigh strap and still keep that famous Leatt non-slip fit. This knee guard meets all of our design criteria. By changing over to 3D-shaped impact gel, we achieved the minimalistic slim shape, whilst still keeping the CE Impact protection.Once you put these on, you will see what we mean! Has a Leatt protection score of 11.
