Costa Del Mar unisex adult Costa Keeper Leash, Costa Blue, 20 Inch US

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.

Exactly what I was looking for.

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.

Big and bulky. Great color. Super soft. Strong. Love them

No issues with assembly. Less than 30 minutes per chair. The chairs with a matching round white Polywood table looks great especially with 4 cushions. The chairs are sturdy and should look nice for years to come.

Not at all what's pictured. Different color. Thick and bulky.

Quality of material is nice and soft. Great way to keep an eye on your expensive sunglasses

This is not the first Costa Del Mar nylon chord that I have used on my Costa fishing glasses . It’s light ,comfortable long enough and works great keeping my expensive fishing glasses on me and not in the water . Joe R
