The Costa Del Mar Rinconcito 9016 Sunglasses bring West Coast surf culture and serious optical performance together in a medium-fit rectangular frame. Named after the legendary Southern California point break, the Rinconcito is the more compact sibling of Costa's popular Rincon model, designed for anglers, boaters, and outdoor enthusiasts who need reliable sun protection without the bulk.
Costa 580 Lens Technology: Glass vs. Polycarbonate
The Rinconcito 9016 is available with Costa's proprietary 580 lens technology in your choice of glass (580G) or polycarbonate (580P). The 580 designation refers to the specific light wavelength—580 nanometers—that these lenses filter out to enhance contrast and color. By blocking harsh yellow light, the lenses make reds, greens, and blues pop, giving you sharper vision on the water and in bright conditions.
The 580G glass lenses deliver exceptional optical clarity and are virtually scratch-proof, making them ideal for saltwater environments where you need to wipe salt spray off your lenses frequently. They're 22% lighter and 20% thinner than standard polarized glass. The 580P polycarbonate lenses are lighter, more impact-resistant, and budget-friendly, with Costa's C-Wall coating for added scratch protection. Both options are fully polarized and block 100% of UV rays.
Bio-Resin Frame & Prescription-Ready Design
The frame is constructed from bio-resin nylon derived from castor oil, part of Costa's Kick Plastic initiative to reduce petroleum-based plastics. This eco-friendly material is lightweight, durable, and holds its shape under extreme heat and cold. Integral spring hinges provide flex and comfort, while Hydrolite rubber nose pads and temple grips prevent slippage even when you're sweating or wet.
The Rinconcito features a 6-base curve—flatter than many sport sunglasses—which makes it extremely prescription-friendly. If you need Rx lenses, this frame accepts a wide range of prescriptions without the optical distortion common in highly curved frames. The rectangular shape and 60mm lens width suit medium faces and work well on both men and women.
Who It's For
Reviewers consistently mention the Rinconcito's versatility. It performs on the boat, the golf course, and during everyday wear. The polarized lenses cut glare on water, snow, and pavement, and the medium fit works for people who find the larger Rincon too big or wraparound styles uncomfortable. If you want Costa's legendary lens quality in a frame that doesn't scream "fishing sunglasses," the Rinconcito delivers.

Frequently Asked Questions
What's the difference between Costa 580G and 580P lenses?
The 580G lenses are made of glass and offer superior optical clarity and scratch resistance—they're nearly impossible to scratch and ideal for saltwater use. The 580P lenses are polycarbonate, making them lighter, more impact-resistant, and about $50-100 less expensive. Both are fully polarized, block 100% UV, and feature Costa's 580 technology that filters yellow light to enhance contrast and color.
Can I get prescription lenses in the Costa Rinconcito 9016?
Yes, the Rinconcito is prescription-ready and extremely Rx-friendly. Its 6-base curve (flatter lens design) makes it one of the best Costa frames for prescription lenses, as it minimizes optical distortion. Costa prescription lenses are available in both 580G glass and 580P polycarbonate, and you can get single vision or progressive lenses while retaining full polarization and UV protection.
How does the Rinconcito fit compared to the Rincon?
The Rinconcito is smaller and designed for medium faces, while the Rincon is an extra-large fit for bigger heads. Both share the same rectangular shape, frame technology, and lens options, but the Rinconcito has a more compact overall size. If standard sunglasses fit you well, the Rinconcito is likely the better choice; if you typically need XL frames, go with the Rincon.
Are Costa Rinconcito sunglasses good for fishing and water sports?
Absolutely. The polarized 580 lenses eliminate glare from water surfaces and enhance contrast, making it easier to spot fish and read the water. The bio-resin frame is lightweight and won't slip thanks to Hydrolite rubber grips. Many anglers prefer the 580G glass lenses for saltwater because they can be wiped clean of salt without scratching, though the 580P polycarbonate is also popular for its impact resistance.
What is Costa's bio-resin frame material?
Costa's bio-resin is a plant-based nylon derived from castor oil, part of their Kick Plastic sustainability initiative. It's lightweight, durable, and resistant to heat and cold, while reducing carbon emissions compared to petroleum-based plastics. The material holds its shape under harsh conditions and is used in all of Costa's plastic sunglass frames, including the Rinconcito.
Do Costa Rinconcito sunglasses have UV protection?
Yes, all Costa 580 lenses block 100% of UVA, UVB, and UVC rays. The lenses also filter high-energy visible (HEV) blue light at 580 nanometers, which can contribute to eye fatigue and long-term damage. Combined with full polarization, the Rinconcito provides comprehensive eye protection for extended time outdoors.

Costa Rinconcito 9016 vs. Rincon 9018: Which Fit Is Right for You?
The Costa Rinconcito and Rincon are essentially the same frame in two different sizes. Both feature Costa's 580 polarized lens technology, bio-resin construction, Hydrolite rubber grips, and integral spring hinges. The key difference is fit: the Rinconcito is a true medium, while the Rincon is extra-large.
Choose the Rinconcito 9016 if: You have an average or medium-sized face, you want a versatile frame that works for fishing and everyday wear, or you find wraparound styles too bulky. The Rinconcito's 6-base curve also makes it the better choice if you need prescription lenses, as the flatter design minimizes distortion.
Choose the Rincon 9018 if: You have a larger head or broader face structure, you typically need XL frames, or you want maximum lens coverage for deep-sea fishing and high-glare environments. The Rincon offers a wider field of vision and more sun protection around the edges.
Both models are available in the same lens colors and frame finishes, and both accept prescription lenses. If you're between sizes, the Rinconcito is the safer bet—it fits most people comfortably without looking oversized.
