Cablz Zipz XL Adjustable Eyewear Retainer | Adjustable, Lightweight, Low Profile, Off-The-Neck Eyewear Retainer Strap | Black

I had some Chums. However, it would not fit on a Costa Del Mar, Reefton Pro. The tips on the arm of the Reefton Pro were way too big for the Chums. So, I saw this on Amazon which was listed as an XL tip and gave them a try. They fit perfectly. If you have sunglasses or glasses with the tips on the arm being very large, give these a try.

I'm a 35+ year kayak fishing enthusiast, and I have used and worn the finest sunglasses from all the major vendors, Ocean Waves, Costa Del Mar, Smiths, & Maui Jim's and every single pair have had Cablz on them for safety and eliminating losing them to the river, creeks and the ocean! I ordered the longer 16" with the XL ends, and I goofed up as my new Costa sunglasses did not have the larger ends on the bows, so I should have ordered the standard size ends, other than that, these like all Cablz, are perfect, great price point and arrived free s/h and super fast delivery. it's all good on my Cablz end.

When they fit they are great ... for a short period of time ...They come in different lengths and are somewhat adjustable, but if the cables are too long, you are screwed if you want to use the cables to tighten glasses to your head. In addition, you have to figure out how to match the neoprene (?) to the temple tipsThe neoprene(?) that wraps around the temple tips wears out quickly so the cables just fall off

Really the best ones on the market. I love them. That one ordered boot was shredded in the package but I still give it five stars even though I have to return it. Also, these break after about six months to a year. I believe a combination of oil on your body and wear and tear cause the boots to split. Make sure you get a boot large enough for your glasses. Even though they came broke in the package, AND they break after one year, these are the best on the market!!!!!

Love these. They work well and last long. They do not get all tangled up.

I have purchased several of these products for various eyewear I own. It is very well made with sliding adjustability which is great when you are doing activities such as skiing, golfing etc. Strongly recommend.

Easily adjusted & most durable eyewear retainers in my experience.

I really wanted to like these. After a couple of months, the plastic bead that secures the wire to the rubberized piece popped off and the wire slid right out. I was simply removing the glasses and let them drop to my neck, when it broke. Seems like they should be a little more durable than that.
