I love these retainers!

If you're looking for a functional way to retain your glasses that doesn't involve placing them on top of your head, this is the way to go. I was concerned that the ends of the retainer would be too small for the arms of my glasses, but that wasn't the case; they fit perfectly. (I have something similar to the "MEC Ashton Sunglasses").

A word of caution to those who would want to frequently remove and re-install the retainer; They fit snuggly and it will be inconvinent to take them off and put them back on. Having said that, it can be done, it just won't be convenient. Once they're on, they are best to be kept on.

I had a pair of Chum's Ranchero's that lasted for years. They were the only sunglass strap that had rubber tips small enough to securely hold my Oakley Romeo 1 sunglasses. I ordered a replacement set and one for my Oakley Badman sunglasses. Chum's sunglass straps stand up to stress (from pulling), rain, snow, and heat. They're Minnesota tested. I recommend them for any Oakley sunglass with a narrow ear sock. Great product, well worth the price.

the little angled end really helps keep your glasses on when you're looking down. Very comfortable and secure.

Stylish and sleek, great fit.

Nice tight fit over the ends of my glasses. What I like about Chums vs Croakies is that the attachment for you glasses with Chums is not obtrusive or visible in your peripheral vision.
