Chums Switchback Retainer

Me gusto mucho es practico de buenísima calidad y se acopla a cualquier tipo de armazón ya sea de sol o graduada pero por la estructura se ve mejor para lentes de sol

Seems to be a great fit.

Excelente producto.

I would have given it a 5 star, it's perfect and exactly what I ordered EXCEPT for the stupid word CHUMS on the side!!! Which by the way is not on the picture. Good one dingbats!! I ordered these.....ERR the ones in the picture with no wording for my dress-up sunglasses, but I will be walking around with CHUMS on the side.

Who buys this kind of product without wanting a way to tighten them in back so your glasses stay in place? Not me. I thought I was getting that feature when I bought these "Eyewear retainers."I see in the description it doesn't specifically claim that it holds the glasses snug. If that's what you are looking for, these are not that. It doesn't help the amazon shows in the 'Similar products' carousel products that DO have that feature.Since I still needed to buy what I originally sought, I bought a different pair. that did have the feature Turns out these, however, are not returnable -- making me even more unhappy about this purchase.I suggest manufacturer or reseller clarify that these are like librarian glasses holder that do nothing to hold your glasses snug while you wear them.
