The Giro Register MIPS Helmet is a sleek, well-ventilated lid designed for the everyday cyclist and daily commuter seeking an affordable option that's upgraded with MIPS technology. Standing for Multi-Direction Impact Protection System, MIPS places a low-friction elastomeric liner that rotates independently around your noggin in the event of an angled impact. Ultimately, this helps to dissipate rotational forces that would otherwise be transmitted through the helmet, which is a glaring vulnerability in the protective design of traditional helmets. Besides the upgraded MIPS technology, the Register MIPS features lightweight In-Mold construction with 22 sculpted vents for heat-dissipating comfort when it's scorching outside. Giro's Roc Loc Sport provides micro-adjustments with the turn of a dial, wrapping your head with a secure, non-slip fit. The Quick Link visor keeps the sun from blinding your vision, especially when you're navigating across cities with shiny buildings and riding along coastlines with glaring sunshine. And to ensure visibility later in the evening, reflective accents shine brilliantly to passing motorists that would otherwise have difficulty seeing you.
