Some of the best features, such as In-Mold construction combined with the straightforward, comfortable, and popular Roc Loc Sport fit system, provide the versatility you need to tackle all biking adventures, from narrow fire roads to steep single trails. Additionally, the Roc Loc system is seamlessly integrated with the Multi-Directional Impact Protection System (MIPS), which can redirect energy and offer more protection at certain impact angles. Features include Roc Loc Sport Fit System, integrated MIPS technology, removable visor, complete hardbody shell, quick-dry padding, reflective elements, and an In-Mold polycarbonate shell with EPS liner. Universal Fit: 54 - 61 cm. The MIPS (Multi-Directional Impact Protection System) consists of a movable shell inside the helmet that follows head movement (10-15 mm) and dampens any rotational energy that may occur during falls to protect the brain. The Roc Loc Sport Fit System offers easy one-handed operation with a 7 cm adjustment range. With comfort similar to the Roc Loc 5 and compatibility with ponytails, the Roc Loc Sport Fit System brings premium functionality to the level of sports helmets. In In-Mold construction, the robust polycarbonate outer shell is bonded to the impact-absorbing EPS inner shell during the foaming process in one step. This makes the helmet even more resilient without adding extra weight. This production process also allows for significantly better ventilation systems and ventilation openings to be formed. In-Mold helmets are therefore lighter compared to traditional helmets and have significantly better ventilation systems. Giro's Universal Fit family helmets fit most people right from the first try-on. The unique universal fit, combined with easy-to-use and comfortable adjustment systems, ensures a perfect and secure fit.
