Built for On-the-Water Performance, Styled for Every Day
The Costa Del Mar Inlet is a performance fishing sunglass designed specifically for women anglers and adventurers who refuse to choose between function and style. Constructed with a durable nylon frame, spring hinges for a secure all-day fit, and Costa's renowned 580P polarized polycarbonate lenses, the Inlet delivers serious optical performance in a silhouette you will want to wear well beyond the water.
Costa 580P Lens Technology
The "580" in 580P refers to Costa's proprietary lens spectrum. Most sunglasses block the harmful wavelengths below 400nm, but Costa's 580 lenses go further. They cut harmful high-energy blue light (HEV) in the 400-580nm range that standard lenses pass through, while simultaneously enhancing reds, greens, and blues for sharper contrast and truer color. The result is a lens that makes structure, current lines, and baitfish easier to read beneath the surface.
The "P" denotes polycarbonate construction, Costa's lightest and most impact-resistant lens material. Polycarbonate is inherently shatter-resistant and among the most durable options for active use, making it the right choice for anglers, kayakers, and anyone spending long hours in bright conditions.
C-WALL Scratch-Resistant Coating
Every 580P lens is treated with C-WALL, Costa's proprietary scratch-resistant coating applied at the molecular bond level. Unlike coatings that sit on top of the lens surface and can peel or chip, C-WALL integrates into the lens itself for durable, long-lasting protection against the abrasions that come with active use on and off the water.
Frame Construction and Fit
The Inlet frame is built from injection-molded nylon, a material prized in performance eyewear for being lightweight, flexible under impact, and resistant to heat and saltwater exposure. Spring hinges at each temple allow the frame to flex outward without losing its return tension, keeping the glasses firmly positioned during casting, paddling, or any activity that puts stress on the fit. The rectangular wrap silhouette provides broad coverage against direct and peripheral glare.
Sight Fishing and Everyday Versatility
The Inlet is rated excellent for sight fishing, the demanding discipline of spotting fish through the water's surface glare at distance. The 580P lens's color enhancement and HEV cut make shallow-water targets stand out against sand, grass, and structure. Beyond fishing, the same optical properties make everyday activities in bright sun, overcast conditions, and high-glare environments noticeably more comfortable. Costa specifically notes the Inlet's strength in cloudy-day use, where the lens's contrast enhancement does the work that flat light removes.

Frequently Asked Questions
- Are the Costa Del Mar Inlet sunglasses polarized?
- Yes. The Inlet uses Costa's 580P polarized polycarbonate lenses. Polarization eliminates horizontal surface glare from water, roads, and wet surfaces, making them effective for fishing and outdoor activities in bright conditions.
- What does 580P mean on Costa sunglasses?
- 580 refers to Costa's proprietary lens spectrum that cuts harmful high-energy blue light up to 580nm while enhancing color contrast. The P stands for polycarbonate, Costa's lightest and most impact-resistant lens material.
- Do Costa Del Mar sunglasses float?
- Standard Costa frames, including the nylon-framed Inlet, do not float. If water safety is a priority, Costa offers separate floating straps and retainers that can be added to keep the glasses tethered.
- What is C-WALL on Costa lenses?
- C-WALL is Costa's scratch-resistant coating applied at the molecular bond level directly to the lens surface. It provides durable protection against everyday scratches and abrasions without the risk of peeling that can affect surface-only coatings.
- Are the Costa Inlet sunglasses good for fishing?
- Yes. Costa rates the Inlet as excellent for sight fishing. The 580P lens cuts glare, absorbs high-energy blue light, and enhances color contrast to make it easier to spot fish and structure through the water's surface.
- Are the Costa Inlet sunglasses good for everyday use?
- Yes. Costa describes the Inlet as one of its most versatile styles, rated for everyday activities and specifically noted for performing well in cloudy conditions where the lens's contrast enhancement is most useful.
