Pinlock is the best innovation in the full-face helmet realm since the advent of the chin strap -- it offers a double-pane-window mechanical anti-fog performance that just plain works.

And this one comes with a side benefit -- it transitions from clear to light-smoke tint automatically depending on the ambient sunlight.

Note that while this pinlock insert will transition to light smoke, it won't go all the way to super dark — for that try the Dark Smoke or Chrome Mirror shield.

In sunshine, Pinlock’s ProtecTINT lens changes from clear to light smoke in seconds to dramatically reduce glare. ProtecTINT returns to clear in nighttime and low-light situations. In wet weather and high humidity, Pinlock’s patented Dry Hydrophilic lens technology absorbs and holds moisture so you can see virtually fog-free.

• Pinlock lens features Dry Hydrophilic moisture absorbing technology for fog-free vision
• Sun-reactive ProtecTINT technology adjusts from clear to light smoke for perfect vision in all conditions
• Pinlock lens is pre-installed on highly scratch- and impact-resistant molded polycarbonate Gringo S/SV shield
• Biltwell Gen 2 hinge hardware included for fast, easy installation
• This shield will not work with the old R22.05 Gringo S helmets, due to the closure being upgraded

NOTE: Do not use standard household cleaners (bleach, ammonia, Windex, etc.) or petroleum-based chemicals to clean any part of the Biltwell shield or the Pinlock lens. Doing so will destroy the anti-fog and photochromic properties of the sun reactive lens assembly. Mild soapy water and a lint-free microfiber towel is sufficient to clean the inside and outside surfaces of the shield/ProtecTINT lens assembly.
