DETAILS Superior Comfort and Adjustability Six years ago, Giro set a new standard in quality, look and feel in a recreational helmet with the original Register. The Register II Youth takes this to the next level by bringing styling and venting of Giro's highest-end road helmets into this lightweight, in-mold helmet in a Universal Youth size for younger riders. With a removable visor, a highly-adjustable fit system and the Mips® Evolve Core rotational energy management system, the Register II Mips is a best-in-class recreation helmet. FEATURES - MIPS® EVOLVE CORE — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards.

The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets. - ROC LOC® SPORT FIT SYSTEM — The Roc Loc Sport 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. - DEEP INTERNAL CHANNELING — Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.

All you need is an active data signal when you start your session. And if you haven’t completed your ride within that time frame, ANGi will send a notification to your contacts with your last uploaded location. - ANGi is a ride tracker, crash detector, and safety beacon. - Includes a one-year subscription to Specialized Ride Premium app. - Detects and reports potentially dangerous helmet impacts to the Specialized Ride app, which notifies your emergency contacts and sends them your most recent GPS coordinates. - Additional premium features include start ride notifications and ride-time alerts. - Attaches to Specialized ANGi-ready helmets. - Approximate six months' battery life on a 2032 coin cell battery. - Weight: 10 grams w/ battery - Two-year sensor warranty
