Shark Skwal Spartan Pinlock Insert

The Pinlock system is based on three basic principles, which together work like nothing else. Unlike the visor the Pinlock insert lens is made out of a soft and porous moisture absorbing material. The thicker materials of these lenses absorb more moisture and offer more impact protection. The airtight pocket between the Pinlock insert and the visor creates an extra insulation layer, further increasing the anti-fogging properties of the total system. Fogging up is a thing of the past. Pinlocks are very easy to fit and very easy to change between tints etc or just keep it clear. The choice is yours! Cheaper than replacing your visor! Fits the Shark Skwal Spartan motorcycle helmet. This is the clear version.
