Costa King Tide 8: Shark-Inspired Design & Top-Tier Performance

High-performance, Innovative, Comfortable, Durable, Stylish

Sometimes, in the big blue theater of the world, it's all about perspective. What you see, how you see it, and more importantly, what you don't see, can make or break a great day on the water. Now, my friends, let me introduce you to a piece of craft that's more than just a fashion statement, it's a tool – the Costa King Tide 8 sunglasses.

Priced at $349, it might cause a moment of hesitation. “Are sunglasses worth that much?” you might wonder. But once you explore the magic within this piece of eyewear, you'll understand the price tag.

Picture this. You're out on the water, the sun is high, reflecting off the shimmering waves. That's where the King Tide 8 comes into its own. Designed with removable side shields, it reduces the glaring intensity of the afternoon sun bouncing off the water, ensuring you're not distracted by the mirror-like surface below you.

These aren't just sunglasses, they're a piece of performance gear designed to stand the test of time and tide. Offered in two sizes, a medium wrap for the less-weathered faces, and a full wrap for the grizzled mariners among us, it's a product designed with diversity in mind.

A unique feature, inspired by the deep blue's apex predator, is the shark gill-like arm vents. With these, the fear of lens fogging, that nemesis of clear sight on the water, is virtually eliminated. And those sweat management channels? They ensure that no drop of perspiration ever dares to trickle into your eyes.

Weighting at just a pound, these frames stay true to their position, even when the water gets rough. That's a blessing that any old sea dog or river rat would appreciate. Polarized with a sleek Black Pearl frame and a base curve of 8, this is eyewear designed for the hardcore among us.

With its Blue Mirror 580G lens, 60mm in width, and an arm length of 120mm, this is arguably the techiest fishing frame on the market. Built for those who demand performance on and off the water, this might be the gear that keeps you a step ahead in your game.

So, if you're one of those elite anglers or if you simply crave for the best view of the vast, unpredictable, and ever-changing theater of water and sky, give these sunglasses a try. They just might change the way you look at the world.
