Giro Adult Ratio MIPS Snow Helmet 2026

About This Item

From its In Form™ Fit System that lets you customize the fit to its adjustable venting that provides airflow when you need it, the Ratio™ MIPS® helmet lets you make all the adjustments you need to stay comfortable on the mountain.


FEATURES:

  • INTEGRATED MIPS® BRAIN PROTECTION SYSTEM — All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro's Integrated MIPS® -equipped helmets is to reduce rotational forces while enhancing fit and comfort by combining the MIPS® slip plane with the helmet's adjustable fit system. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts. Learn more about MIPS® in the video above.
  • HARD SHELL CONSTRUCTION — Hard Shell Construction produces great helmets at a great price. A rugged outer shell is molded and then attached to the EPS foam liner.
  • SEAMLESS COMPATIBILITY — For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggles for an exceptional fit and dependable, worry-free function.
  • STACK VENT TECHNOLOGY — Our Stack Vent was developed based on research showing the majority of warm air that can cause fogging comes from the goggle's center top vent. Aligning the Stack Vent in the helmet with the center vent of the goggle helps keep it clear and fog-free.
  • THERMOSTAT CONTROL — Thermostat Control Adjustable Venting allows you to custom-tune airflow instantly with a simple, low profile control button on the outside of the helmet. No other system is faster or easier to adjust, and nothing is more effective at keeping you comfortable.
  • VERTICAL TUNING — Accommodates different goggles and head shapes for a custom fit free of gaper gap
  • IN FORM FIT SYSTEM — The In Form Fit System makes it easy to dial in a custom fit in seconds - even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6cm of adjustment and enhanced stability.

    Cool And Safe!

    Bought this for my son for snowboarding and he says it’s very comfortable and I like the look of this helmet on him and I feel better with the MIPS safety!

    Not What I Had Hoped

    This version of the Giro helmet was a lot heavier than others I had tried. It was comfortable but the additional weight was substantial compared to the more expensive Giro Neo helmet. I returned it and spending a bit more $$ to get the lighter version

    Good Value

    It has same features as the more expensive models. Very happy with this purchase. Used but have not crashed in it so cant speak to how it holds up.

    Great Helmet

    Very happy with this purchase. Bought in store, so I was able to try it on and make sure I liked how it fit. Took a spill on the mountain and was glad I was wearing the helmet, definitely prevented a serious concussion.

    Great Features . Great Ventilation. Durable

    My son loves this helmet as it has ventilation on top that can open or close so he doesn’t over heat.
