HJC i10 Helmet Clear Pinlock Lens Insert (for HJ-31 shield)

Pinlock lens insert for HJC HJ-31 face shields, which fit HJC i10 helmets. Pinlock technology keeps your vision fog-free by sandwiching a layer of neutral air in between the outside of the visor and the inside of the helmet. Just like a storm window, this insulated layer of air prevents fogging. Far superior to so-called fog-resistant chemical coatings, this mechanical anti-fog device is the best way to beat fogging up your helmet shield, bar none. Easy to install, these inserts are a must-have for riders seeking clear vision and safety in all weather conditions.Thie particular insert is designed specifically for the HJC i10 helmet.
