The Giro Seam is a long-standing favorite helmet for skiers looking for great ventilation and comfort. A single large Stack Vent keeps air moving across the top of your goggles to eliminate fogging. The Thermostat Control utilizes 12 vents to regulate your temperature, should you start to overheat. Vertical Tuning helps the Seam be very compatible with other goggles to adjust the fore and aft tilt, even though it has a seamless compatibility with all Giro Goggles. Giro has added an X-Static Anti-Microbial Padding that keeps your helmet fresh for seasons to come. An In Form Fit System provides up to 4cm of adjustment for a perfect fit. If you are looking for a helmet that has its own look, with the protection you need to ski day in and day out, the Giro Seam is the helmet for you.
