The Giro Source MIPS Helmet offers industry-leading protection thanks to the MIPS (Multi-Directional Impact Protection System) technology. It’s also supremely comfortable thanks to the CoolFit antimicrobial padding, which wicks away any sweat from your head on warm days. The 16 ventilation zones encourage airflow to keep you cool and dry, while the easy-to-adjust Roc Loc 5 system ensures you can find the perfect fit with a twist of the dial. The visor moves up and down to suit your eye line. GIRO Source MIPS® Bike Helmet | Ultimate Outdoors
