Pacific Coast threw one of these in when I ordered 6 pair of KDs for the wife and I. I dont normally wear these as the KDs stay firmly on my head even at high speeds. My wife however really loves it! She hasnt left her glasses at the stops yet this year.

dont recall ordering the retainer now wish youd have sent 2. one for each pair.

Looks good. Keeps shades right where I need them. Very handy

Would be better with a strap that can be tightened. Harder to put on graphics, but more useful to keep these light glasses on your head when you are riding.

They work well while my hubby is on his bike.
