About this item

  • *SIZE XL (62.5–65cm)* CONSTRUCTION - Hard Shell construction produces great helmets at great value. A rugged outer shell is formed and then attached to the EPS foam liner.
  • FIT SYSTEM - 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. Vertical Tuning feature accommodates different goggles and head shapes for a custom fit free of gaper gap (space between goggles and helmet).
  • VENTILATION - 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. Stack Vent in the front of the helmet which aligns with your goggles and helps to keep them clear and fog free.
  • SEAMLESS COMPATIBILITY WITH ALL GIRO GOGGLES - Giro products have been meticulously designed and tested to work together. We've fine-tuned the pairings of our helmets and goggles using exhaustive testing in our Dome R&D center and translating those findings into the perfect Seamless Compatibility fit. We recommend Giro Roam and Moxie Goggles.
  • FEATURES - Compatible with aftermarket Giro audio systems by Outdoor Tech.


The Ratio Mips helmet has the perfect ratio of everything you need to accompany you on the mountain, from its Thermostat Control Adjustable Venting to its Mips technology to its laid-back style.

Nice helmet that fits well and is adjustable. However, my goggles do not match the brim of the helmet leaving a space. I tried my other goggoles and the same thing, does not fit well with the brim.

Nice helmet, my son likes it but the goggles strap broke on his first day out, hence 4 stars. I think the actual protective qualities and fit are more important, so I would still recommend.
