My Costa Del Mar Sunglasses Review: Why I Won‘t Wear Anything Else
As an avid boater and fisherman with over 20 years on the water, I‘ve gone through more than my fair share of sunglasses.
Cheap pairs that scratched after a few trips. Designer brands not cut out for all-day tropical sun exposure. Odd specs that never quite fit right on my wide head. You name it.
But finally, about 5 years ago on a buddy‘s recommendation, I took a chance and splurged on my first pair of Costa Del Mar sunglasses. And I‘m happy to report after countless days spent fighting blazing sunlight, salty sweat and even the occasional fish hook – they‘ve held up flawlessly and kept my vision sharp through it all!
In this Costa Del Mar sunglasses review, I‘ll be sharing my impressions as a half-decade owner across four different frames. Quick spoiler: I firmly believe Costa makes the highest performance polarized lenses money can buy. I won‘t wear anything else these days.
And it‘s not just me. As Costa‘s grown over 30+ years in business, they‘ve expanded from niche fishermen brand into one of the most popular and fastest growing sunglass labels worldwide.
My History Finding That Perfect Pair
I still remember the endless eye strain from squinting at the water for hours pre-Costa way back when. Trying to spot subtle bait swirls or lurking weedlines with the afternoon sun beating directly down. It gave me near-migraines after lengthy outings capped with dueling headaches and seasickness.
Not exactly ideal boating conditions. Especially when trying to relax and crack open a cold one with the boys after docking.
I experimented with various cheaper sunglass options thinking maybe I just needed darker tinting or broader temple coverage or amber lenses for contrast. Nothing really moved the needle.
Fed up after a disastrous offshore charter losing multiple hooked tuna I never even laid eyes on, I finally asked my sportfishing influencer buddy James with 20/20 vision what glasses HE wears daily.
"Dude…just get some Costas. Nothing else comes close for spotting fish and eye relief when you‘re on the water sunrise to sundown like us. They ain‘t cheap but I‘ve had this one pair going strong for 6 years without a single scratch. 100% worth it if you‘re serious about what we do out here man."
That glowing endorsement was enough to convince me to bite the bullet and invest in a quality pair of Costa 580P Blackfins with blue mirror lenses I found on sale for around $150.
And his claims turned out right on the money.
Finally no more squinting at the sea searching for signs of life! It was like gaining built-in telescopic vision with how much more visible bait balls, debris and underwater structure became. Fish I couldn‘t spot before now glowed with enhanced vibrant colors and definition.
Suffice to say, I was sold pretty much instantly after that maiden voyage. Over many more trips, Costas instantly improved my catching ability. I went from averaging 3-5 fish per 6 hour trip to regularly boating 10-15 keepers.
That extra visibility and stamina adds up greatly when trying to locate schools of tuna or mahi blitzing offshore. Not to mention eliminating eye fatigue so I can fish sunup to sundown!
Nowadays pretty much my whole crew including dad and little brother rock Costas in some form as our shades of choice on the regular. The value and performance simply can‘t be beat in my experience.
Let‘s expand on why…
The Nitty Gritty Behind Costa’s Legendary Lens Technology
See Costas didn‘t randomly stumble into becoming a leading sunglass maker known the world over. There‘s some serious optical materials science and innovation powering their rise with purpose-built lens technology designed specifically for high glare environments.
In a nutshell, all Costa lenses feature specially formulated lightwave filtering polarized film built directly into the lens material itself rather than flimsy external films added as post-processing in cheaper brands.
This allows precise manipulation of incoming light waves by:
- Blocking intense reflections
- Removing specific wavelengths causing eye fatigue.
- Enhancing contrast and natural color vibrancy.
The result? Unmatched clarity and visual acuity translating into big benefits on the water.
For example, cutting surface glare improves subsurface visibility picking out lurking structure, bait and predators. Enhancing color and contrast keeps eyes from tiring as quickly for all-day endurance. And filtering selective light spectrums magnifies the vividness of coral, foliage and underwater creatures compared to the naked eye.
Costa accomplishes this optical wizardry through patented lens material technology in two distinct offerings:
580P Plastic Lenses
Constructed from impact-resistant copolymer blends with the light filtering properties embedded directly in. This makes them extremely lightweight while protecting against shattering.
I suggest 580P lenses for all-around durability especially in high risk usage where scratching or dropping remains likely. They lack some clarity of glass options but still deliver phenomenal optics for most.
580G Glass Lenses
Taking things up a notch, these lenses get molded from ultra pure glass allowing Costa‘s engineers to fine tune optical clarity down to a microscopic scale. Removing any impurities or distortions.
The result? Water-piercing sightlines rivaling mineral crystal. Colors and details pop like an HDR filter cranked to the max. If ultimate optics rank high on priority, splurge for the 580G lenses.
Just be aware glass comes with added weight and risk of fracturing upon high velocity impacts. I reserve my glass lens pairs for casual days fishing smaller lakes and rivers. But some buddies swear by them offshore fishing as well.
To each their own!
No matter which material you select, rest assured you‘ll be gaining immense visual performance over cheaper plastic fantastics. Let‘s cover which frame styles put that technology to work in top form.
Reviewing Some of My Favorite Costa Frame Offerings
With over 70+ frame shapes and sizing combinations to flip through, pretty much any head size or preference gets accommodation by Costa‘s extensive lineup.
Let me highlight just a few stylish best sellers that I‘ve personally tested and would enthusiastically recommend.
Blackfin Frame

My first pairs rocking blue mirror 580P lenses. Love the slimmed rectangular shaping with understated matte black finish. Plus the adjustable nose pads prevent any slip downward when I sweat.
I‘d classify the Blackfins as more sporty than flashy. But still pulls compliments whenever worn out around town. Hard to beat the comfort-to-style ratio.
Fantail XL Frame
When I need max coverage on the brightest offshore days, the Fantail XL model comes through with substantial curvature wrapping 180 degrees. The satin teak colors exude that salty captain vibe.
While definitely not the most attractive, I‘ll gladly sacrifice some looks for high volume light blocking capabilities the Fantail XL delivers in spades. Side glare all but gets eliminated which proves crucial spotting distant radar blips or flocks of diving birds signaling bait converge below.
Highly recommended for the hardcore fish hunters.
Loreto Frame

For casual wear knocking around the marina or enjoying Apres-fish brews waterside, I‘ll break out the Loretos when wanting to blend in with non-boat shoe crowds.
The sleek metallic aviators style bridges the gap nicely between refined and rugged. I also use my Loreto 580Ps for twilight night fishing when lack of harsh overhead light becomes less impactful.
Many More Where That Came From!
The frames above just scratch the surface of Costa‘s deep option inventory. Whether you need slender wire frames to squeeze into a racing helmet or oversized wraparounds to guard rail thin cheeks from angle exposure – Costa has thoughtfully addressed pretty much any sizing requirement or style preference.
Price Breakdown: Are Costa Sunglasses Expensive & Worth It?
Alright time to confront the sailfish in the room. Let‘s chat pricing!
There‘s no skirting around the fact Costa sits firmly in the premium bracket when it comes to sunglass costs. Their models typically range from $149 entry-level frames all the way to $299 for special collab models rocking the latest exclusive lens colors.
With many cheaper alternatives available, fair question arises – is this pricing ultimately justified?
In my experience, the answer is a resounding YES for three key reasons:
1. Bombproof Durability
Across four frames over 5+ years of fishing, I‘ve yet to have a single lens scratch or frame break that wasn‘t fully covered by one of Costa‘s generous warranty replacement policies. We‘re talking glasses that have been dunked, stepped on and met all kinds of abuse without flinching.
The build quality and ruggedness simply rises above everything else I‘ve tested. So while the upfront cost exceeds cheaper brands, you end up saving substantially over time not having to continually replace shattered pairs every year or two when inferior construction fails you.
2. Clarity Beyond Comparison
It didn‘t take long fishing side-by-side with buddies wearing cheaper polarized glasses to witness firsthand the visibility gap Costas deliver.
I‘d be calling out floating debris and submerged structure they completely missed. And hooking double…triple the numbers because I could accurately decipher faint bait swirls or passing shadows they struggled picking up.
When livelihoods depend on split-second sightline accuracy, Costa delivers every time. Makes the price tag fade consideration quickly when that superior vision directly converts into fatter offshore paydays.
3. Lasting Support & Warranty
This gets overlooked but carries tremendous hidden value. Costa proudly stands behind their lenses and frames forever.
I‘ve had multiple repairs covered fully under warranty over the years after accidental drops causing small scratches or dings. Each time the replacements arrived within 2 weeks – often brand new frames with zero out of pocket costs.
Not many companies offer that level of no-questions-asked support. So you‘re buying quality AND peace of mind.
Add those three pillars of value up and suddenly the prices become much easier to digest. When treated as a long-term investment into protecting your vision pursuing passions, Costa delivers worthwhile ROI multiplier times over.
Costa Owner Reviews: Do Actual Customers Agree?
Don‘t just take my word on Costa‘s excellence. Thousands of verified owners echo similar sentiment…
"Costa‘s warranty and durability is unmatched. I‘m on my 8th year golfing daily with the same pair. Left them on car bumper and backed over them. $29 no hassle later for replacement lenses and frames and good as new. Love it!"
4.8 out of 5 stars (Jose C.)
"I guide fish the Florida Keys year-round and Costas allow me to see into the water better than any other lens. I need that visibility spotting blacktip sharks cruising through waves so we can cast ahead. Going 10 years strong on this pair!"
5 out 5 stars (Capt. William Y.)
"I beat my glasses up bad working summer construction but my matte green Costa Fantails still look brand new after 4 long seasons. Saved me so much not having to re-buy cheap pairs that got destroyed. Love that they come with insurance!"
5 out of 5 stars (Marcus P.)
The praise continues across thousands of reviews with Costa owners positively giddy having gained such a massive quality of life upgrade through enhanced sharp sightlines that hold up admirably even under extreme regular use.
Heck even the pickiest critics sporting Costa‘s more expensive graphite frame models with premium add-ons report overwhelmingly positive long-term ownership experiences.
If consistent visibility and construction count (and they ALWAYS do on the water), Costa reigns supreme.
Final Verdict: Costa Del Mar Sunglasses Hit The Trifecta
Hopefully this complete guide gives helpful perspective answering that burning question…
Are Costa Del Mar‘s expensive sunglasses ultimately worth the investment?
In my experience owning four pairs over thousands of hours spent on sun-drenched seas, when adding up:
✅ Unparalleled optical clarity
✅ Bombproof ruggedness
✅ Generous lifelong warranties
The answer becomes clear. Costa delivers top-shelf quality and craftsmanship creating that "final pair" of shades. No more guessing games finding temporary solutions.
While cheaper than some designer brands, the financial outlay EXCEEDS value return through extra fish brought in and long-term savings on replacement pairs down the road thanks to that bulletproof build integrity.
So if chasing performance and longevity keeping eyes peeled in harsh environments ranks high in priorities, Costa wins my highest recommendation. Just be sure to shop sales and discount retailers to help offset costs.
Your vision and passion pursuits deserve dependability. Costa brings both in spades!
