Product description

An affordable modern helmet that is second to none with much more expensive models. Under the hood, you'll find an easily adjustable In Form clamping system, full Thermostat ventilation control or antibacterial linings. Compatibility with Giro ski goggles is guaranteed - we recommend the Roam, Cruz, Boreal or the women's Moxie models.

Main advantages:

  • Hard Shell – The durable outer shell is shaped separately and then bonded to the inner EPS liner
  • In Form Fit System - 6cm range, tightening by ergonomic wheel
  • Vertical tuning- helmet height adjustment
  • Thermostat Control - adjustable and lockable ventilation
  • Stack Ventilation - goggle ventilation support
  • Compatibility with all Giro goggles
  • CE EN1077 Certification

Technology:

In Form™Fit System
The In Form Fit system allows you to easily adjust the helmet size by up to 6 cm in seconds, even with gloves, using the Ergo-friendly wheel in the back of the helmet.

Vertical Tuning
With the vertical shift option, the helmet easily adjusts to different goggle and head shapes, so it fits you snugly with no gaps between your head and face.

Certification:
CE EN1077
