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.
Bottom Line:
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!
