The Giro Ledge MIPS is a perfect helmet for high-flying park skiers with a minimalist look. This skate style design features MIPS (Multi-Directional Impact Protection System) that uses a low friction liner that rotates upon impact to absorb energy, instead of your head taking the blunt of the impact. A Removable Goggle Retainer and Ear Pads allow you to sport the freestyler look by wearing your goggles and a beanie under your lid. Stack Vents move air into your goggles to prevent fogging. Giro's Auto Loc 2 Fit System is self-adjusting with an elastic band that is secured to fixed position straps for a secure and safe fit when you are crushing it in the park, launching off a giant booter, or urban assaults in places you are not supposed to be.
