    It gets the job done without you noticing.

    You won't even notice the ultra-thin C-Line Sunglass Retainer by Costa Del Mar around your neck. But you will notice how easy it is to keep your sunnies close by when you step into the bait shop to grab whatever's hatching.

    Poor design

    • Familiarity: I've used it several times
    • Fit: True to size

    In short, they do what they're supposed to do -- keep you from losing glasses. Costa tried to reinvent the wheel here and go with a cable-like, ultra thin design. The problem is that it doesn't rest nicely on your back, but sticks out at odd angles and is uncomfortable. You can't really store the glasses with this on unless you guy another case that's bigger. I will post a picture, they're just weird. I'd recommend saving your money and buying something else. Or I'll just give you mine, I don't want it....

    Too long and too cheap

    • Familiarity: I've used it several times

    Bought this as a replacement for my cables that I loved but lost. I run pools so I am in and out of water all day every day. I thought this would be an acceptable substitute but was instantly disappointed with the quality and fit. The wire is much too long and sticks way out when being worn. 3 days in, one of my daughters pulled slightly on my glasses and the wire pulled through the rubber attachment. There is no bead holding them in like cables have and also no way to repair them once they are pulled through. Cheap knock off in my opinion and expected more from Costa. Back country was great with shipping, no issues with them.
