The Giro Seam Helmet is Giro s classic, bomber freeride lid for the serious all mountain athlete. Super solid In-Mold construction and a one-hand adjustable Thermostat Control system make the Seam the go-to helmet for more mountain professionals than you can count on.
In-Mold Construction In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.
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 Ventilation Stack Ventilation 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 your goggles helps to keep them clear and fog free while maintaining total helmet and goggle integration.
Super Cool™ Vents 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.
In Form™ Fit System A low-profile fit and stability system that makes it easy to dial-in the fit and feel of your helmet in seconds – even with gloves on. An ergo-friendly dial at the base of the helmet provides up to 6 cm of fit adjustment, and the system also includes a separate vertical turning feature that adjusts the fore / aft tilt of the helmet on your head to enhance peripheral vision and optimize the fit of the helmet with goggles.
Vertical Tuning All Giro helmets with integrated fit systems feature Vertical Tuning. Vertical Tuning dials in how the helmet sits on your head for a perfect fit, eliminating gaper gap and creating a seamless lockup with Giro goggles.
X-Static® 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 reduce odor and regulate heat.
Seamless Compatibility with All Giro Goggles For optimal performance of both helmets and goggles, Giro products are designed to work together. Ensuring a seamless interface between helmet and goggles offers exceptional fit and dependable, worry-free function.
