12 Super Cool Vents with Thermostat control: Super Cool™ vents pull cool, fresh air into the helmet while pushing heat and stale air out. By maximizing efficiency and optimizing vent shapes, the collective cooling power of Super Cool vents helps to regulate your core temperature and keep you feeling fresh all day

Thermostat™ ventilation control 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™ was developed based on research showing the majority of the warm air that can cause fogging exhausts from the center top vent of the goggle. Aligning the Stack Vent in the helmet with the center vent of y our goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration.

You can easily fit a pair of goggles over or under the Giro Seam Helmet.

– 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 while the vertical tuning feature accommodates different goggles and head shapes for a custom fit, free of gaper gap.

Compatible with all after market TuneUps systems

In-mold construction: fuses a tough polycarbonate outer shell with the helmet’s impact absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets

Super Fit™ Engineering is the foundation of Giro’s product design process. Every new Giro product is designed with reference to their database of anatomic measurements and rider input. They then test the design repeatedly in the lab and in the hands of riders so they can gather feedback and make refinements to create a final product that fits and performs at the highest level

X-Static® is a fiber made with a layer of pure silver, which is permanently bonded to the surface of a textile fiber. It is an antimicrobial fiber that is 100% natural that helps to reduce odor and regulate heat
