Performance Technology:
Costa 580 Lenses:
Beyond Polarized:
Costa 580 lenses were designed by in-house light spectrum experts to enhance colors because standard sunglass lenses fell short. The lens’ multipatented technology manages light by:
Absorbing Harmful High-Energy Blue Light (HEV):
Cuts haze and blur for greater clarity
In addition to 100% protection from UV light, 580 technology also absorbs HEV light known to cause macular degeneration, pterygium, cataracts and other eye diseases
Enhancing Reds, Greens, and Blues:
Blocking harsh yellow light at 580 nm on the visible light spectrum boosts the amounts of red, greens and blues naturally, enhancing colors and contrast
Filtering Out Harsh Yellow:
For enhanced color, sharper contrast and higher definition

Lens Technology:
Light conditions are constantly changing. To get the most out of Costa lenses, it's important to choose the right color. Costa Del Mar offers seven lens colors that range from low-light like dawn to extremely bright light with blinding glare.
Choosing a Lens Color:
Light conditions are constantly changing. To get the most out of Costa Lenses, it's important to choose the right color. Costa offers seven lens colors that range from low-light like dawn to extremely bright light with blinding glare.
For offshore, blue mirror is the way to go. For freshwater and inshore, green mirror and copper are great options. For low light at dawn or dusk, sunrise silver mirror is perfect. Gray lenses are the best choice for everyday activities. Of course, the best way for you to decide is to consider your environment.

Lens Color:
Blue Mirror:
Best for bright, full-sun situations on the open water and offshore.
Gray Base
10% light transmission
 
Optimal Usage:
Boating and fishing in deep water

Frame Qualities:
Costa offers frames to meet everyone's needs. Customers can choose a frame based on color, hypoallergenic materials, durability, lightness, cost and uniqueness. Each frame offers its own performance advantages and style features for eyewear that fits every occasion.
Co-Injected Nylon Frames:
The nylon frames are tough and durable, with more color options manufactured using the environmentally friendly bio-resin process. TR-90 nylon is a premier material for sports and performance frames as it is resistant to heat and cold. Though it is flexible, it is still durable. Nylon is easily molded into wraparound and other shapes.
Frame Materials:
Tri- Lateral Fusion
Costa is the industry leader in this manufacturing process.
Original bilateral and trilateral styles are created by bonding together two or three distinct colors into one frame.
Each layer is comprised of solid color bio-resin. The result is a highly durable frame with chip-proof color.
Costa offers multiple unique color combinations in both bilateral and trilateral styles.
Quality Hinges:
The corrosion-resistant, stainless steel flexible hinges keep their shape and fit perfectly.
They come in three types:
Integral
Optical spring
Five-barrel optical

Nice quality but questionable fit!
Color: Navy 09, Size: Large
I recently purchased the Alex Vando Mens Golf Shirt in size Large. The fabric quality has a good feel to it — it feels smooth, breathable, and the moisture-wicking seems to work well during light activity. However, the sizing and fit were inconsistent. I ordered a Large, but when I tried it on, it was somewhat tight and fitted around the mid-section, despite not saying "slim fit". I would say I am average size: 5' 9", and 195 pounds. I were a size Large in 98% of the clothing I purchase. This was more like a size Medium - Long. That said, the shirt is also very long! Like, abnormally long. If you're tall (over 6'), this shirt will be perfect. But for anyone else, it won't fit quite as nice. I had to return it as I think an XL would be huge on me!

Sexy jacket!
Size: XX-Large, Color: Blue
I want to first say that the jacket looks exactly as pictured the color is very spot on it's not too washed out and not too blue. I bought it for my male partner, It really gives him the rugged look without making him look intimidating or too much like an emo boy. I'm thinking hipster style. Secondly, you have to size up if you are intending to wear this jacket on top of a sweatshirt or anything thicker than a t-shirt. I'm so glad that I read reviews before purchasing this because if I had bought his size it would have fit him but he would not have been able to wear a sweater or sweatshirt under it. My partner is tall and about an XL in sizing. The jacket stops just at his waist and accentuates how tall he is. Sleeve length is perfect. I will also say that it's not super thick, it's a great fall jacket just good enough to stay warm in brisk weather. This is more of a fashion piece than it is a coat. Something that no one mentioned is there are two large pockets on the inside of the jacket that my boyfriend loves because he can now hide snacks in them. This jacket honestly gives me New York Street fashion vibes and I love it so much I plan on stealing it from him time to time.
