Giro has developed the Bishop for riders who are looking for the classic Giro fit but need an extra large size. Inspired by the clean lines and serious ventilation of the Revel and Verona models, this helmet is equally at home on and off the road. Its in-mold construction makes it lightweight, but without compromising durability. For maximum comfort, the Acu Dial system allows for easy, individual fine-tuning of the helmet seat at any time. In-Mold ConstructionIn-Mold construction, the tough polycarbonate outer shell is bonded to the impact-absorbing EPS inner shell in a single operation during the foaming process. The helmet becomes even more resistant without additional weight. This production process also makes it possible to produce significantly improved ventilation systems and vents.
