New to Costa? The Fantail lineup makes use of the 360-degree co-molded technology. The key detail in construction is in the non-slip Hydrolite lining which is along the interior of the Fantail frame to help the sunglasses stay put at all times.
Costa Del Mar Fantail Sunglasses have a tough, rectangular frame with a medium fit but can fit a few wearers with slightly large heads. The co-injected nylon construction guarantees comfort and durability. In fact, it takes up to the challenges in saltwater environments.
Costa is an American manufacturer of high-quality polarized sunglasses. Though a subsidiary of the Essilor, their sunglasses have gained popularity in the sports market and have been rated among the best for outdoor activities like fly fishing.
Costa takes a very keen interest in environmental conservation and sustainability through recycling plastic waste from the fishing nets collected in the ocean. Through a partnership with Bureo Company, the nets are recycled to pallets which are used by Costa to make the frames.
Fantail Sunglasses are available in a wide range of frame colors. If you intend to buy them, you can select a lens option that fits your outdoor lifestyle. Colors for polycarbonate lenses are amber, copper, and gray while glass is available in silver mirror, green, blue, copper, amber, and gray. 580 lenses by Costa are among the clearest so far.
It doesn’t matter whether they are glass or polycarbonate. Glass remains most optically clear and highly scratch resistant. Polycarbonate is lightweight and impact-resistant.
Costa uses different material and coatings to make their lenses. What cuts across all of them is delivery- amazing clarity, color, and contrast and the deepest part is seeing your world in the purest form.
Normally, yellow light is a known enemy to eyesight. It becomes difficult for the eyes to process and change how you see things when yellow light hits your eyes.
580 lenses make the blue, green, and red prominent while greatly reducing yellow light. What you get is sharper contrast, deeper colors, and purer vision.
Lens Material – Upon identifying your perfect fit, you can decide on the Lightwave or polycarbonate lenses. Fantails are available in polycarbonate lenses and glass lenses. Polycarbonate is lighter, less costly and more durable, unlike glass lenses. Remember, your taste and preference are important here.
Lens Color – Costa lens tints guarantee you full safety from the effects of intense sunlight. The ones in this review are Blue Mirror and are excellent on open water and offshore.
Other available lens colors are Green Mirror for high contrast, Gray Silver Mirror suitable for everyday activities, Copper Silver Mirror for natural contrast, and Gray for everyday activities.
Sweat and Heat Management – Fantail’s new model allows for a sufficient flow of air through the end of the frame. This allows for cooling and reduction of fogging on the lenses. Nose pad ventilation hasn’t been introduced on this model but is present in the Tico and Broadbill.
Nose and Temple Pads – Nose and temple nose pads on the Costa Del Mar Fantail Sunglasses are made from textured Hydrolite to help in managing sweat and heat. They also ensure a secure fit necessary for all-day comfort.
New models have durable pads, unlike the older Fantails that had the pads dropping off after a few months.
Hinges – Costa makes amazing hinges that are well-crafted from high-quality stainless steel that is corrosion and rust-resistant. Flexibility is a pass to ensure the frame’s shape is maintained.
Coating – The Costa C-WALL lens coating actively repels water, dust, oil and dirt. It is also responsible for the lenses’ scratch resistance feature.
Polarization – Fantails have a record of excelling in fishing by cutting glare off water allowing anglers to see a greater distance beneath the water. It is easy to identify fish, rocks and other aqua life when having the polarized glasses on than without.
UV blockage – We recommend lenses with 100% UV protection and Fantail falls here. It blocks all harmful UVA, UVB, and UVC rays. This keeps your eyes safe from cataracts, pingueculae, and photokeratitis.
Frames – Costa uses the co-injected bio-based TR-90 nylon type frames on Fantails for increased toughness and durability. The material offers a comfortable and amazing fit. This makes them usable in saline environments because they don’t rust or corrode like metallic frames. The fusion of Hydrolite and nylon prevents slippage hence great optical alignment. They stand up to the challenge.
Accessories – Once you purchase legit Fantails, they come with a zipper storage case and a microfiber cleaning cloth. Costa recommends the C-mono retainer for the Fantail, the Costa strap, a clarity kit, a halyard wire retainer and a dry case. They aren’t compulsory for use with the Fantails but you can get them if your budget allows.
Fit – The manufacturer has adjusted the Fantail to fit medium-size heads. The new model has improvements in the distance between the lenses, has a flatter head curve and nose pads that are deeper and adjustable.
Warranty – Costa issues a limited lifetime warranty to the original owner of every pair of sunglasses. In case of defects in construction and other issues causing malfunction stated in the warranty, the manufacturer will sort it out.
Customer Thoughts on the Fantail Sunglasses
There are so many reviews criticizing the authenticity of these Fantails. Remember that there are original Costa Fantails and imitations which are made by quack companies.
Fakes don’t fold completely when you close the arms, springs that hold the arms will back out very soon and everything about them is not real.
ALWAYS buy from authorized dealers. These customer thoughts section is based on the original Costa Fantail Sunglasses and not the fakes that come cheap and full of garbage.
Plastic lenses are lighter than glass lenses on the bridge area when worn and have good visual aspects like the glass one. The glass lens is superior on acuity.
To check on authenticity, keying the numbers on Google brings the Costa Del Mar Fantail Sunglasses picture. You can’t be spending so much on trash.
The coating is awesome and very difficult to scratch. You can’t compare the polarization and filtering with other big names out there. They are excellent on the bright ocean and the reflective features on snow and water are incomparable.
Fantails are excellent for cutting glare on water and are comfortable for all-day wearing. They take away the eyestrain and sooth the eyes wonderfully. If you are zealous enough you can catch more than your limit.
No wear and tear on the zipper case a few years down the line. The nose pads make the sunglasses stay put at all times even without the retainers on. The frames too fit comfortably and don’t press on the temples.
Temporal fogging on the lenses has been witnessed by a few users especially when room temperatures change dramatically.
Older models of the Fantail had issues with the rubber nose pads falling off but the new model has greatly been improved and this doesn’t happen anymore.
The sunrise lenses are yet to pass the ANSI Z80.3 traffic signal recognition requirements and are not recommended for use while driving.
