Not all days are spent riding aggressive terrain. Like freshly groomed resort corduroy, the all-new Oakley MOD3 with MIPS protection was redesigned with crisp lines. Engineered with a lightweight shell and featuring an evolution of our Modular Brim System (MBS), the all-new MOD3 is the go-to helmet for all-mountain riders, and with the inclusion of MIPS - Multi-Directional Impact Protection System the all-new MOD3 provides the ultimate in brain protection. Redesigned for the 2018 season, the all-new MOD3 has an updated design aesthetic and the integration of adjustable venting, allowing the wearer to dial in the helmet ventilation that's the perfect for them. A 360-degree BOA closure system delivers full wraparound comfort while securing the helmet fit. The evolution of the Modular Brim System allows wearers to choose between a brim or no-brim aesthetic without jeopardizing goggle integration and the redesigned ear pad and head liner feature X-Static fabrictechnology.
