Giro Instigator Sunglasses. All business up front, with performance and plenty of attitude to back it. The Instigator is a perfect fit for riders who want strong and sophisticated style that's as functional on the trail as it is on the way to the beach. D
Strengths: Durable, I am brutal on glasses. These have lasted 4 years which alone is a feat!
Good look, cheap I got em half off in 2008 so if you CAN find them they likely will be a good purchase.
Weaknesses: none yet. Maybe the rubber head "clamp" pieces degrading and breaking down over the years…but they still are there. Just the rubber "ear holders" no longer clearly say "GIRO"…but really 4 years on my noggin and this is all I can come up with. I should note - the rubber ear pieces are still there just worn down slightly.
Great buy, considering they likely will be on sale. Well made lenses, no eye strain. The fell on your head - these disappear when on, which is the sign of any great cycling equipment…you forget about the equipment and enjoy the ride!
