13 Best Costa del Mar Sunglasses Retainers

Sunglasses are perhaps one of the best inventions in the history of mankind. Seriously, they protect your eyes from UV rays, reduce glare and dim reflections. All while making you look cool! Sadly, sunglasses tend to fall off, get scratched, and break. But luckily, a good Costa sunglasses retainer can help.

A Costa sunglasses neck strap has a piece of fabric that attaches to the arms of your glasses. You can then wrap it around your neck, providing extra security when your sunglasses aren’t in use. These kinds of straps are great when you’re cycling, fishing, or doing other outdoor activities where there’s a high chance that your glasses might fall off.

In this article, we’ll help you with how to choose a Costa sunglasses retainer. This way, you won’t end up wasting your time and money on some dubious products. But before we get to that, let’s check out some of our reviews below.

Costa del Mar Fathom Cord

10

We decided to purchase the Costa del Mar Fathom Cord for our kayaking adventure in Colorado. Straight out of the box, we noticed that these retainers come in a ‘librarian’ style, meaning that the straps will go around the arms of your glasses instead of sticking out the ends. In other words, you won’t have wires hanging in front of your ears, which is perfect when you’re doing activities that require you to wear a helmet.

The sliders in Fathom Cord work great. They provide a tight grip, and you can adjust them according to your liking. We’ve taken this Costa sunglasses retainer to a variety of rugged environments, and the rubber part is anything but loose. They have been exposed to the sun and saltwater many times. We honestly think that Fathom Cord is of good quality. If you decide to look for a new retainer for your glasses, this will be perfect.

But for a better fitting, you can spray a little hairspray or any kind of lubricant. Trust us; they’ll make your life much easier!

We’ve done a lot of cycling this summer, and there have been countless times we’ve accidentally dropped our sunglasses. That’s why this Costa sunglasses neck strap is a blessing.

Shopping online always makes us a little nervous. Sometimes you don’t know what you’re getting or when they’ll arrive. That’s why we appreciate the fact that Costa Gripper Leash ships fast. As soon as we received the straps, we put them on the ends of our glasses, and they fit perfectly. We even ordered another pair for our trip, and they came just as fast.

Another thing to love about this Costa sunglasses retainer is its swivel connection. You’ll need to drill holes to make it work optimally, but it’s completely secure and locked in place.

Costa Loop

5

One of the problems with eyeglass retainers is that they have annoying snap swivels. They can make constant noise around your ears, catch your hair, and bang your head all the time. Luckily, there was the Costa Loop to save the day. These straps have a low profile. It won’t hit you in the neck or the back of the head. However, please note that the Loop only works with Costa sunglasses with a cut slot on the back of each earpiece.

In order to secure the retainer, you don’t need to pull any rubber clamps. All you have to do is get the end of the flexible loop through the hole. We have to admit that this isn’t the most intuitive mechanism ever. But on the brighter side, it works! If you’re looking for a Costa sunglasses neck strap and hate snap swivels, the Loop would be a remarkable choice.

  • No annoying swivel. This retainer utilizes a loop mechanism which is much simpler and works much faster.

3

Glasses are generally not going well with physical activity. They tend to fall off or come off when you move around a lot. But with the Cablz Zipz Eyewear Retainer, you can keep your precious sunglasses in a safe place, no matter how active you are. These straps have a low profile and are almost impossible to notice. They keep your beloved shades hanging around your neck when you’re not wearing them. You can also make them rest on top of your neck or your head!

Another great thing about these Costa sunglasses neck straps is that they’re fully adjustable. Plus, they can easily slip under your helmet or hoodies. And thanks to the patented ball bearing technology, the Cablz Zipz Eyewear Retainer will stay away from your neck. Keep your sunglasses safe without hurting your skin!

Croakies Retainer

2

Croakies Retainer is made for demanding tasks. One user on Amazon claims that he’s a former paratrooper and that Croakies has helped him keep his sunglasses safe during various jumping missions. We didn’t have a chance to do some serious testing on this Costa sunglasses retainer. However, we did notice that these straps were a little tricky to fit into our sunglasses, and that’s a great thing! Had they been too easy to fit, our sunnies would slip or fall off easily.

As for build quality, the Croakies Retainer is apparently well built. Unfortunately, the only way to adjust the length of this retainer is to thread the temples of your glasses further up the sleeves. So if you have a smaller head, you need to put in more effort. Overall, this is a nice product. We just wish Croakies added some kind of bearing or adjusters for easier adjustment.

• What We Love:
  • Nicely constructed, provides a tight grip, and is relatively easy to install.
• Pros:
  • Imported
  • High-quality neoprene
  • Hypur Cell

  • Doesn’t come with adjusters

Neon Neckz

If you spend most of your time on the water, Neon Neckz will be awesome. This Costa sunglasses neck strap is equipped with a floater. In case your sunglasses fall off with the straps, they’ll stay afloat, allowing you to locate and have them back immediately. Just make sure to go with lighter colors, as they’re easier to spot in open water.

Neon Neckz has a small diameter. You may find it quite difficult to get these straps into the arms of your sunglasses. However, a little olive oil or lubricant will definitely help. On the brighter side, the retainer will give you a tighter grip. Other than that, they feel great and look tough. Overall, we’re really happy with this purchase.

• What We Love:
  • Keep your sunglasses floating, just in case they fall into the water
• Pros:
  • Come with a floater
  • Colorful straps
  • Comfortable
  • Affordable

How to Choose The Best Costa Sunglasses Retainer

Although they all basically have the same basic function, each Costa sunglasses retainer is actually made to serve a different purpose. They come in different materials, sizes, and colors. As always, you need to decide based on your needs and situation.

To make your life easier, you need to consider below some crucial factors in choosing a Costa sunglasses neck strap. Keep reading for further explanation.

Material

Comfortable and sturdy are two mandatory qualities of a Costa sunglasses retainer. Therefore, you need to look for a neck strap made of flexible plastic, neoprene, or tough cotton. This is important since you’ll have the strap hanging around your neck and touching your skin directly when your sunglasses aren’t in use.

Compatibility

Next, make sure that the neck strap you get is compatible with your sunglasses. A Costa sunglasses neck strap for the aviator is made specifically for thin frames. Meanwhile, there are some other eyeglass retainers that are made to work best with thicker frames.

And speaking of sunglasses, did you know that cat-eye sunglasses are one that never goes out of style? If you’re interested in having a great pair at home, then check out our best cat eye sunglasses for women.

Color

Last but not least, think about color. A good Costa sunglasses retainer should blend well with your outfit and frame. It would be much better if the retainer expresses or elevates your personal style.

What is a Sunglasses Strap Called?

Some people refer to them as eyeglass retainers. They’re basically a piece of fabric that connects the arms of your sunglasses, so you can hang them behind your head or around your neck. That way, you can keep your sunnies safe while you’re not wearing them.

How do you use eyewear retainers?

First, fit the straps into the arms of your sunglasses. Next, get them to the back of your head or around your neck. If you want a tighter grip, adjust the bead as desired.
