What Our Gearhead® Experts Are Saying: "The Union MIPS checks every box for me—comfortable, well-vented, and the fit system makes on-the-fly adjustments super easy. I love how it integrates perfectly with my Giro goggles, and the anti-odor padding actually makes a difference after sweaty laps."From first tracks to last laps, we count on the Giro Union MIPS Helmet for lightweight protection, a dialed fit, and all-day comfort. This all-mountain performer blends safety tech with smart features that help us stay focused on the line ahead—not fussing with gear. The in-mold construction reduces bulk and weight, while the MIPS system provides added peace of mind against rotational forces. Ventilation is fully adjustable on the fly, and Stack Vent tech keeps our goggles fog-free even during storm laps. The In Form Fit System gives us a snug, stable fit with a quick turn of the dial, and the XT2 anti-odor padding stays fresh through back-to-back powder days.
