The Montaro MIPS II Helmet from Giro keeps us protected when we're swerving on singletrack and traveling through the trees. MIPS impact protection guards against rotational forces in the event of a crash, and a polycarbonate shell improves on durability and structural integrity. We like that the Roc Loc 5 Air fit system dials in our ideal fit for comfort, and the internally channeled ventilation that keeps us cool when we're working hard.
