With a vision enhancing low profile frame and classic style, you'll be fully stoked on the Giro Semi Goggle with Bonus Lens. Based on the Blok goggle, the Semi is scaled down a bit to fit smaller faces without compromising field of view or performance. Expansion View Technology is a fancy way of saying this goggle sits closer to your face and is tapered slightly downward so you see less of the frame and more of your surroundings. Seamless compatibility with all Giro helmets ensures a comfy fit when you're wearing your brain bucket and means you'll never have to worry about dreaded gaper gap. Double layer face foam with a microfleece lining offers a comfortable and cozy fit, and an anti fog coating keeps your lens crystal clear when you're shredding in a storm. Plus, it comes with a bonus lens so you can be ready for changing light conditions.
