  • Love every pair of Costas I’ve ever owned
Color: Matte Clear/Blue Mirrored 580g Size: 64 mm
I love these sunglasses. I have about 4 pairs of costa’s and they are really the only brand I’ll buy. The 580g lenses are fantastic for fishing. I really like the clear frame, that was something I haven’t had before. These fit snug but not too tight for my big old gourd head. I really like the fact that there is a rubber lining on the sides of the frames, that isn’t something I’ve seen on my other pairs that I really liked about these. It’s a really effective addition to keep these snug on my face while bending down on the boat or leaning over the side. They’re not too heavy even with the glass lenses. While I love the lenses, I know I’ll only get so long with them since they’re glass. The clarity is awesome and the tint is perfect, but glass always breaks at some point. My last pair of Fantails were great but the glass split horizontally right in the middle of the lense for no reason at all. Never dropped or sat on them or anything and because they were a gift, I can’t get them replaced… no proof of purchase. My ONLY complaint about costa is the lack of being able to easily get OE replacement lenses easily. There’s a million knock offs, but I like their 580 technology. I have found a company that makes some polyurethane lenses, not polycarbonate, and they are $99 total and they will ship you a box and replace them for you and the lenses seem virtually indestructible as well as providing super high clarity at a lightweight. Wish costa wouldn’t be so stingy about their lenses… anyway, these glasses are awesome and look killer! ... show more

  • Incredible fit, incredible lenses!
Color: Matte Black/Grey 580g Size: 64 mm
I've been using these Costa Del Mar sunglasses for a few weeks now, mainly for driving and outdoor walks in sunny Los Angeles, and they are seriously impressive. I've attached a picture to show real-world clarity. The 580g easily cuts through the sun's glare while driving, and it enhances the vibrancy of brighter colors. Wearing them feels as if someone put a clarity filter on my vision, haha. They are generally lightweight but a bit heavier than the Ray-Bans I usually wear. The additional weight does not negatively affect me, as I have found that this frame has a snug and comfortable hold. The build quality feels very durable and premium - the lenses repel smudges fairly well and are very easy to clean with the included wipe. Overall, I think they are fantastic value from Costa! They don't come cheap but I think these feel like they will last and perform well for a very long time. ... show more

  • Great quality!
Color: Matte Black/Blue Mirrored 580g Size: 64 mm
I have a pair of Costa Del Mar sunglasses so I know they are excellent quality sunglasses. They may be a bit pricey but not anymore than any other high quality sunglasses. My husband loves them! They are a perfect fit. He has worn them quite a bit and says they are lightweight, very comfortable and don’t pinch or feel tight around his ears. They come with a durable zippered sunglass case. The polarized lens clarity is great and offers really good protection in the sun. My husband loves the blue color of the lens and they look very stylish. The blue says it’s best for bright light so perfect for my husband since we spend a lot of time on the water. The blue polarized lens really cuts down on the glare especially when you’re on the water. These really are great sunglasses if you spend a lot of time outside. Both my husband and I can highly recommend these sunglasses if you’re looking for great eye protection that is well made and very stylish! ... show more

  • Great pair, but a bit tight
Color: Matte Black/Copper Silver Mirrored 580g Size: 64 mm
Another great pair of Costa sunglasses. I've loved every pair of Costas that I've owned and these are no exception. The build quality is fantastic and and the lenses are crystal clear. The polarized lenses are phenominal too. The Fly Line sunglasses are a bit tight on my face and the ear pieces dig a little into my head so they aren't the most comfortable pair own for long time wear. I'm a bigger guy with a big head and these would definitely fit a smaller head better. Overall happy with the shades and I'll be letting my teen son use them for now. ... show more

  • High Quality Wraparound Sunglasses
Color: Matte Black/Copper Silver Mirrored 580g Size: 64 mm
These men's sunglasses are beyond nice. They're functionally made extremely well, and everything from the materials to the hinges to the lenses are just great quality. They are extremely durable, and so far they're perfectly scratch resistant. The lenses are polarized, and they work to make everything you see so much more vivid than with regular lenses The fit is definitely made for a larger face, and they look so good on. They're a wraparound style that feels very sporty, and the color of the lenses against the black of the frames really pops. Overall, these and any of the Costa Del Mar sunglasses my husband and I have ever had are all quality and stylish, and I definitely recommend them. ... show more

  • I do like the brand, but this particular model was not for me
Color: Matte Tortoise/Grey 580p Size: 64 mm
134 mm arms way too big make sure when you buy these glasses you understand the measurements of your face

  • Great sunglasses for fishing in the Gulf.
Color: Matte Black/Grey 580g Size: 64 mm
This is my first pair of Costa’s and now I see why a lot of my friends choose this brand. I have a couple pairs of high end sunglasses but none are as nice as these Costa Del Mar for fishing. The polarized lens are sharp and have excellent clarity and color. The quality is top tier and the lens are scratch resistant, which is a major factor when I look for new glasses. These sunglasses fit me well and don’t slide off my nose when I look down, and I have a pin head (still plenty of room for my pea brain though). Overall, these glasses are great for most any outdoor activity and are a real value for the money. ... show more

  • Nice glasses
Color: Matte Black/Green Mirrored 580g Size: 64 mm
Good value—price is comparable to most big brands. These fit well, are comfortable, and seem to be well made. The lenses are nice and clear and work well in many lighting conditions (cloudy to full sun). This is my first pair of Costas (typically wear Oakleys), but would purchase this brand again.
