"Loved the glasses when they arrived, but after using a couple of times both arms snapped off while stored in their case. Gutted as apparently this is not covered by the warranty"

"My all around favorite running glasses! Zero bounce, and perfect vision."
— Robin (5/5)
"I have been wearing Smith glasses for cycling for many years. I had an issue a part on one pair that is not produced any longer. Smith was quick to compensate with a credit and ordered the Defy model. GREAT customer service. Thanks you!"
— Vito P. (5/5)
"Perfect fit for runners with a smaller face! Light, secure, and crystal-clear—my new favorite shades."
— John (5/5)
"Very cool design, great style, great lens, but these do not fit securely into the vents on the Trace helmet or my other helmets vents. My glasses fell out of my helmet during a ride and both arms broke off. I dropped sunglasses enough times and have never had any oakley, roka, or julbo break like these did. They did not refund me either. Strange that the design of the sunglasses is not compatible with their flagship helmet."
