Costa Del Mar Unisex Adult Bowline Silicone Retainer

Love this retainer,,, I’ve had lots in the past and have honestly never liked one as much as I do this one. The quality is excellent. The colors are beautiful and it’s absolutely perfect for my Casta sunglasses, I cannot be more pleased.

Awesome cables for your glasses

I bought these for my safety glasses at work and they fit great. They stretch enough to get the bigger diameter glasses arms in and then they hold tight. They also don’t seem to rub on my neck, most of the time I don’t even notice my glasses dangling.

If you've got large profile temple tips or have a flared out ear piece, then this retainer is not going to work for you. It is likely to split open whilst trying to snug them on the flare. For larger flared out temple tips, go with the 'Costa Del Mar unisex-adult C-line Retainer'. I recently acquired the Saint Laurent frame (SL 505), and it has low profile skinny temple tips. This bowline silicone retainer is perfect with a nice adjustable bead that slides up and down. If your bead slips off, you can get your handy Hemostat Forceps Locking Tweezers Clamps and pull the bead back through with no issues.Some things to keep in mind. if you produce a good bit of sebum or oil on your face and behind your ears, the silicon retainer will break down and disintegrate over time since your oily skin is acidic compared to the silicone rubber. To increase the lifespan of your retainers. wash your glasses and retainer regularly under warm soapy water, and pat dry with cotton fiber towl or some other means, etc. Whatever you use, it should not scratch up your lens or framesl

Product works great. I live in Wisconsin so I only need to wear my Costas a few months out of the year compared to when I lived on the gulf. So I don’t get as quick of wear as I did before, seem to have held up just fine for the past year. Much better than the Cwire one that didn’t relax at all. However my only issue is because I am a female and I have long hair. I wanted an all black keeper and minimally noticeable, since having glasses around your neck isn’t as trendy up here and I just look like an old lady doing my own thing. This was the only Costa brand keepers that was simple and solid black that I could find. The other, Fathom, I’m looking to purchase just has loops so I’m hesitant in it’s keeping ability. So I tried this style. And it is not easy to just throw the strap over my head, pull my hair over it without it getting stuck in my hair and if I’m wearing too many coats during winter it has so much friction when I go to turn my head driving it pushes my sunglasses off my head a little. They don’t allow enough movement with bulky clothes (which isn’t a problem on the beach) or hair that goes past you neck.

Fits well.

I have a pair of Warby Parker‘s that keeps slipping down my nose during activities. These work great, and are very comfortable.
