Ready to hit the trail, tear up the road and even play at the beach? Hop to it with Serfas' Sike-Out glasses. They boast lightweight and form-fitting frames with scratch-resistant lenses that deliver 100% UVA and UVB protection. The lenses are also polarized to reduce glare and help you see contrast better. And, they change tint to match the lighting conditions so you always enjoy great visibility. Meanwhile the wrap-around frames offer additional protection and the shorter temples with tips that curve down behind your ears hold fast. Plus, there are vents to prevent fogging. You'll also like the lack of frames on the bottom of the lenses so you can look down with nothing blocking the view.
