Giro has made the compound MIPS for drivers who need an extra-large size but don't want to do without the proven Giro fit. Inspired by the self-confident mountain bike style and the airy ventilation of the Fixture helmet, the compound was constructed around many of Giro's best features, such as in-mold construction coupled with the uncomplicated, comfortable and popular Roc Loc Sport fitting system. A seamlessly integrated Multi-Directional Impact Protection System, which can divert energy and provide more protection at certain impact angles, ensures you're on the move with the latest in head protection technology.In-Mold Polycarbonate Shell with EPS LinerThe In-Mold construction fuses a strong polycarbonate outer shell with the helmet's shock-absorbing foam padding. The MIPS Multi-Directional Impact Protection System consists of three main components: the EPS Liner, the Low Friction Liner and an elastomeric fastening system between them. Under the influence of rotating forces, the elastomers offer the possibility that the EPS shell can move independently around the head. Helmets equipped with MIPS can offer increased protection in certain situations.Roc Loc Sport MIPS Adjustment SystemThe Roc Loc Sport Fit System offers easy one-hand operation with a 7 cm adjustment range. Its good feel and sound let riders know that the helmet offers a comfortable fit. With comfort similar to the Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport Fit System brings premium function to the level of sports helmets. - Purpose: MTB - Helmet construction: In-Mold + MIPS - Details: - Complete hardbody shell - Quick-dry padding - MIPS - Multidirectional Impact Protection System for additional protection - Material specifications: EPS foam - adjustment system: Roc Loc Sport MIPS adjustment system - special features: MIPS - Visor/Screen: Umbrella - Visor/Screen removable Ventilation openings - Quantity: 18 pieces
