The Register™ Mips® II brings the style of Giro's highest-end road helmets into this lightweight in-mold helmet, adding a removable visor, an adjustable fit system, and the Mips® Evolve Core rotational energy management system, to create a best-in-class recreation helmet. Six years ago, Giro set a new standard in quality, look, and feel in a recreational helmet with the original Register. The Register II takes this to the next level by bringing styling and venting of Giro's highest-end road helmets into this lightweight in-mold helmet. With a removable visor, an adjustable fit system, and the Mips® Evolve Core rotational energy management system, the Register II Mips is a best-in-class recreation helmet. Key Features The two-piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight. All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts. Our Universal Fit helmets are sculpted to look good and fit great for almost anyone on the first try. By developing proprietary shell sizes based on specific customer groups, and combining them with an easily-adjustable fit system, it's easy for you get the right fit, straight out of the box, without the hassle or expense of trying multiple sizes. The Roc Loc Sport Mips fit system offers easy one-handed operation with a 7cm adjustment range. Its confident clicking feel and sound lets riders know that the helmet is adjusting to a comfortable fit. With comfort similar to Roc Loc 5 and ponytail compatibility, the new Roc Loc Sport fit system brings premium function to sport level helmets. Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.

The Roc Loc 5 Led Light is one of the easiest and most powerful ways to increase visibility and safety on the road.

Big Kid Style The Scamp II is Giro's smallest helmet designed for young (or future) riders but it still goes big with features and style. Taking design cues from adult helmets like Manifest Spherical, this lightweight in-mold helmet features impact-dissipating EPS foam with a sturdy polycarbonate shell, plus 13 vents for efficient cooling power. The Roc Loc® Junior fit system provides extra adjustability with a simple-to-use dial for several years of head protection for fast-growing rippers. The XS is designed for riders aged 1 and older while the Small is for riders aged 5 and older. Whether they're rolling along in a trailer or powering the pedals themselves, Scamp II is going to make kids want more bike time. FEATURES - IN-MOLD CONSTRUCTION — In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets. - ROC LOC® JR. FIT SYSTEM — Roc Loc® Jr. is a simple, durable, dial fit system specifically shaped to match the curvature of a child's head. The shape was developed with years of research into anatomic data to ensure a secure, comfortable fit. A large, rubberized knob makes it easy for adults to adjust the helmet for proper tension, allowing kids to quickly start their ride. HIGHLIGHTS XS: Complies with the US CPSC Safety Standard for Bicycle Helmets for Persons Age 1 and Older (Extended Head Coverage) S: Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older
