Nickel-plated stainless-steel snap-on shield fastens securely to snap on the helmet shell. The Gen-2 shields fit all Gringo S models because they come with an all-new baseplate kit. These baseplates have an improved mechanism that results in firmer detents for three open positions. To clean your shield, use mild soapy water solution and a microfiber cloth to loosen bugs and road debris, then dry it with a second clean microfiber towel. Every shield colour and style provides 91% UV/A and 99% AV/B light resistance based on AATCC-138 test standard.
