## Customer Reviews

### ⭐⭐⭐⭐⭐ A Nice Addition for Your Glasses
*by B***C on August 4, 2016*

I purchased this and Costa Del Mar C-Mono Retainer for a new pair of sunglasses. I was planning on returning one when I evaluated both. Instead, I'm keeping both. There are different positives and negatives for both styles of sunglasses straps.**C-Mono Retainer**Positives:WaterproofDurableRetains its shape (doesn't droop or contort)Holds onto sunglasses arms very wellStylishNegatives:Retains its shape (tough to put a pair of sunglasses with a c-mono on it into the sunglass caseRetains its shape (the wire will stick out the back a little so it might bother some people)It's made of metal (metal wire may be a turn-off for some people)**Nylon Keeper Cord**Positives:Holds onto sunglasses wellCan tighten the loop if necessary (hold sunglasses on your face)Soft cord that hangs down (nylon vs metal)Stylish designNegatives:Not waterproof so it will get wet and soggy in waterHangs down close to the collar so it might bother some peopleLikely not as durable as the c-line retainerFIT:Both styles of holders seem to have the same size opening that holds onto the sunglasses. I tested them out with three different pairs of sunglasses and each one was easily attached. I'd estimate this will fit medium/normal to slightly bigger arms but overly large arms probably need an XL opening (see Croakies or Cablz for other top brands).Highly recommend both the c-mono retainers and these nylon keeper cords.

### ⭐⭐⭐⭐⭐ Costa glass strap
*by B***N on August 8, 2025*

Exactly what I was looking for.

### ⭐⭐⭐⭐ Product works, color differs
*by C***A on April 27, 2025*

Product works as described. The color is a true blue color not as a lighter ocean blue like in the product picture. Keeping item, however , the color I received is a true “basic” blue.
