The Giro Crue MIPS is an excellent helmet for any little skier or snowboarder. MIPS (Multi-Directional Impact Protection System) offers more protection by having a low-friction liner that rotates around the head to redistribute impact should your little one take a hard tumble. The In-Form Fit System has a dial that helps you get the perfect fit with just a few simple twists. Super Cool Vents keep a steady flow of air moving through the helmet to prevent overheating and keeping cool. Stack Vents sit on the front of the Crue MIPS that keep air moving through the top foam of your little ones goggles to prevent them from fogging. A Seamless Compatibility with the Giro Rev and Chico goggles make for a perfect fit for your little one to enjoy the slopes.
