Review: For frames that have smaller profile temple tips, this retainer fits really snug. - 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 ## Features - Costa Silicone Retainer: Flexible, durable and lightweight, the Costa Bowline retainer is a streamlined silicone retainer with sliding bead for adjustable tension to make sure your sunglasses stay put, on and off the water. - From end-to-end, the Costa Bowline Silicone Retainer measures 19". - Born on the water in 1983: Costa Sunglasses for men and women is celebrating 40 years of making the premium sunglasses on the planet and protecting the watery world we call home ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D35LY87P | | Best Sellers Rank | #98,524 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #16 in Men's Eyeglass Chains | | Customer Reviews | 4.6 4.6 out of 5 stars (3,374) | | Date First Available | May 14, 2025 | | Department | womens | ## Images ![Unisex Adult Bowline Silicone Retainer - Image 1](https://m.media-amazon.com/images/I/51yyQ9LgXSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very nice *by I***. on December 10, 2025* Better quality than the sunglasses they sent me…. ### ⭐⭐⭐⭐⭐ For frames that have smaller profile temple tips, this retainer fits really snug. *by P***A on February 11, 2024* 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.
