This Pinlock 70 MaxVision is only suitable for the following visors: KDF31 for EXO-930 EVO.
A Pinlock is a lens that is attached to the inside of the visor to prevent fogging. The Pinlock lens is made of a special moisture-absorbing plastic. The silicone seal on the Pinlock lens creates an insulating layer of air between the Pinlock lens and the visor, just like double glazing.
