Go deeper and further with the Giro Trig™ Mips®, a brimmed hard-shell helmet built for freestyle riders who demand comfort, protection, and style. Featuring the Integrated Mips® Brain Protection System and the In Form Fit System, it offers a dialed-in fit and added safety against rotational impacts. Thermostat Control Adjustable Venting and Stack Ventilation keep airflow optimized and goggles fog-free, while the progressive design ensures seamless compatibility with Giro goggles. Whether you're hiking the park or dropping into steep terrain, the Trig Mips is ready to ride.
How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
