To catch the fish, it helps to see the fish.

Standing between you and the bright sun is a school of tuna just ready to be caught, and the Costa Del Mar Tuna Alley Polarized Sunglasses let you see each one. Costa 400 polarized glass lenses block harmful UV rays as well as harsh glares so your eyes can be at the ready for any subtle bites. The glass lenses are also 20% thinner and 22% lighter than standard glass polarized lenses, and they resist scratches so you can enjoy these sunnies for many years of boating and fishing. Costa Del Mar made the frame out of co-injected nylon for durability, and then added vents at the sides to keep your vision crystal clear even in hot environments. An eight base curve means these shades wrap around your face for protection in front and at the sides. Store the Tuna Alley in its hard case when it gets dark and your cooler is filled with a delicious dinner.

It's almost like cheating

  • Familiarity: I've put it through the wringer

The big talk when it comes to fishing is polarized glasses, and how they can improve your fishing game. A friend suggested I pick up a pair of polarized glasses (Ray Ban), and I decided it was time. I'll openly admit I've an Oakley bias, and for good reason - they have proven to provide solid products and handle the abuse my gear under-gos; Oakley has always been there for me. I picked up a pair of Oakley Holbrook - Brown Polarized on sale, but my cousin, a professional fly fisherman in Montana, suggested Costa. Choosing Costa over Oakley was difficult, so I bought both: Costa Tuna Alley (Matte Black - Pol Green Lens) and Oakley Holbrook (Matte Black - Pol Brown Lens). I'll say it again - I'm bias to Oakley, but the Costa lens is absolutely incredible.

My suggestion is this, if you're fishing or doing an activity where color, contrast, and glare are important - give Costa a chance. They're comfortable, they're incredibly clear, and lightweight. The Costa lens provides color vibrance and contrast that my Oakley's cannot compete with, honestly no contest. If you're a fisherman, the reduced glare, increased contrast, and color definition of the Costas are like cheating.

The Oakleys (Brown Pol.) are better for driving and casual beach wear.
The Costas (Green Pol.) are better for active, athletic, outdoor wear.

Keep in mind, not only does company matter and how they design the lens, but so does lens tint as it chooses which wave length of light (colors) to filter or enhance. Look on Costas and Oakleys website, they'll provide more detail to help choose which lens tint will work best (Green = moving water: streams, creeks, and rivers... Blue = open water: lakes and ocean).
