Giro created the Bishop MIPS Mountain Bike Helmet for riders in search of the classic Giro fit but in need of an extra-large size. Inspired by the sleek lines and serious ventilation of the Revel™ and Verona™, this helmet is equally at home on pavement and dirt, and its In-Mold construction keeps it light without compromising durability. The on-the-fly adjustable Acu Dial™ system makes it easy to custom-tune the fit, for maximum comfort and stability. Bishop MIPS options are equipped with the Multi-Directional Impact Protection System. MIPS can provide more protection in certain impacts, and this added technology does not compromise fit, ventilation or style.
