The Giro Ratio MIPS is a perfect choice for skiers and snowboarders looking for a helmet that is loaded with features, but won't break the bank. Vertical Tuning, Giro's In Form Fit System and a Seamless Compatibility with all Giro Goggles makes the Ratio MIPS a simple and easy to fit to protect your squash when you are out on the slopes. MIPS (Multi-Directional Impact Protection System) adds extra protection by having an inner shell that can rotate upon impact inside the exterior shell rather than transferring the energy from the impact towards your brain. Thermostat Control Venting uses a toggle switch on the top of the helmet and strategically placed vents to help you regulate your temperature. A Stack Vent on the front of the Ratio MIPS keeps air moving through your goggles to prevent fogging. If you want added protection, in a package that will leave you extra cash for another lift ticket, the Giro Ratio MIPS should be a no-brainer.
