Named after a reef islet formed by broken coral and sand surrounding an atoll, the Costa Motu Polarized Sunglasses are ready to perform whether you’re cruising around the lake trolling for a trophy-sized fish or basking at your backyard barbecue.


The Motu’s are equipped with Costa’s 580 technology lenses that provide 100% UV blockage for maximum protection and 100% polarization to kill reflected glare. The 580 technology goes beyond polarization to produce the clearest lenses on the planet. It selectively filters out the harsh yellow and harmful high-energy ultraviolet blue light, making colors brighter and objects appear more defined. So no matter what you are doing under the sun, you’ll see it in stunning detail.

The 580 technology built into these lenses is so sharp and crystal clear, I would often find myself excitedly exclaiming to other people around me, “how extremely beautiful the sky and clouds are”, or “hey, look at the color of the sun shimmering off of the water”. No one understood my exuberance, until I shared my shades with them. And then it was always the same question, “Where can I get a pair of these?”

The Motu’s that I tested out were equipped with the blue 580P’s – polarized plastic lenses. Over the course of a month, through the in’s and out’s of just about everything in an over adventurous active lifestyle, these they have remained scratch free. These lenses are the definitive upgrade your eyes have been waiting for!

Costa also offers glass lenses for the Motu, which are best for situations that require ultimate clarity, however do add a bit more weight to the sunglasses.

Choosing a Lens Color

The Costa Motu sunglasses are available in six lens colors that range from low-light like dawn to extremely bright light with blinding glare. Lighting conditions are constantly changing and it is important to choose the right color. Below is the list of different colors available.


The Motu frames are a medium fit that have a relieved face curve for total comfort and an optical-quality spring hinge that hugs the face just gently enough to stay put, but at the same time leaving you wondering if you forgot to even put them on.

The glasses went everywhere with me for over a month, from fishing, to water skiing, road running to trail running, nature hikes to trail rides. I put them through the so called wringer, lost and found them in the lake, had them knocked off of my face in a volley ball death match, and they came out on the other side, blemish free and in exceptional condition.

Hydrolite Temple and Nose Pads

The sunglasses’ Hydrolite temple and nose pads ensured these bad boys stayed put when I was cruising around the lake, running down trail, and riding down the road, even when they were soaked. The TR-90 nylon frame grants a super lightweight comfort, yet delivers the toughness for durability that one expects in a high quality pair of sunglasses.

The Motu frame is not only available in Real Tree Xtra Camo with the orange logo, but three other colors as well; Blackout, Matte Black Teak and Retro Tortoise. With these four frame colors and the six lens colors, the options and style is yours for the making.
