The Vantage was built for the hard-core, demanding the ultimate in everything. Using AEROCORE™ construction that features Koroyd® simultaneously maximises full coverage protection & increased airflow. This is the womens model in stunning blue matte aqua. For the most custom fit, the Vantage offers the Boa® FS360 fit system, with a 360° halo design. Combine all this with the Smith pioneered Air Evac technology for goggle integration, & the Vantage delivers the perfect blend of technology & style.

Love it. It is very light weight, the Koroyd construction is very reassuring in the even of a big impact off-piste, & it felt great on the head even with a Go= Pro on. I have been a Giro man for years (G10, Seam) but the BOA fit system on this helmet is just SO good, & you can crank the helmet right up if you are on bumpy stuff & have the Gopro running, & then back it off in seconds. A fantastic new addition for Edge & Wax!
