C-Mono Retainer

Excelente

Great for my sunglasses

Excelente te producto ajustan muy bien con los lentes Costa calidad muy buena

Comfortable, lightweight, effective. The mono can be a little stiff but I like that because it does not hang on my neck. Also, over time, the rubber does not grip as well. I used a piece of a medium rubber band on my hammerheads and slipped the rubber over the glasses with the rubber band. Grips even better than new and since I leave them on my glasses, it works for me.

I purchased this and Costa Del Mar Nylon Keeper Cord, Blue 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: Waterproof Durable Retains its shape (doesn't droop or contort) Holds onto sunglass arms very well Stylish Negatives: Retains its shape (tough to put a pair of sunglasses with a c-mono on it into the sunglass case Retains 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 well Can tighten the loop if necessary (hold sunglasses on your face) Soft cord that hangs down (nylon vs metal) Stylish design Negatives: Not waterproof so it will get wet and soggy in water Hangs down close to the collar so it might bother some people Likely not as durable as the c-line retainer FIT: 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 nylon keeper cords and these c-mono retainers.

This is a good product. Does what it saids!! However, if you have long hair it will sometimes get stuck on the rubber pieces on end that hold the sunglasses and this does not feel good!! My son likes his. But he has short hair!!

Exactly what I expected. Great quality!

So don't wear if you are wearing a hat with your glasses, super uncomfortable. Still not a bad price.
