Ultra-thin knee pads comprising lycra sleeve and a thin bright yellow Poron XRD padding that’s moulded in place.  The padding is soft and flexible while riding, but on impact it becomes solid to absorb the stresses.  Unrestricted knee movement is made possible by shallow gaps in the moulding.

The thin lycra sleeve is pretty breathable, and the pads are really comfy but the bright yellow is a bit in your face.  The price is good but they are currently only available from the US with a delivery charge to the UK at 20 dollars (about £12.50)
