The Giro Nine.10 Helmet was inspired by the Giro Nine Helmet. More than a decade after the original Giro Nine helmet was introduced, it"s soul lives on in the all new Nine.10. With style cues from our Seam helmet and featuring our legendary In Form fit system, this lid packs a lot of bang for the buck. Make sure you check out our new Weather Strip Vent Shield which replaces hard to keep track of vent plugs.
