Costa Del Mar Rincon II Rectangular Polarized Sunglasses for Men

What you’re really buying here

Costa Del Mar’s Rincon II is a men’s rectangular sunglass with a full, wrap-style frame look (full-rim design). The big headline is polarization—so on paper, it’s built for glare-heavy days when you want your view to feel calmer and clearer. If you spend time on the water, around bright surfaces, or you just dislike that “washed out” feeling from sun glare, polarized lenses are usually the move.

The Rincon II leans more “classic performance” than fashion-only. It’s not a super lightweight, barely-there style (rectangular frames tend to look more structured), and that’s fine if you like a clean outline that holds its shape.

Key takeaways (and what to check first)

Polarized lenses are the core reason people shop models like this. Polarization helps reduce glare, which can make it easier to see contrast and detail when light is strong. The full-rim rectangular design also suggests a more defined frame presence—something that can visually balance your face rather than disappear on it.

Before buying, it’s worth taking 30 seconds to match the fit to your face shape. Costa Del Mar calls out that this rectangular silhouette tends to look best on oval and round faces. If your face is already quite long and narrow, rectangular frames may feel a bit intense, if your face is round, the sharper shape can actually be the right contrast.

The essentials: frame size and face-shape fit

You’ll see the listed dimensions as 64/11/134. Those numbers are there for a reason: they help you gauge how wide the lens area is, how much bridge width there is, and how the temples sit.

In terms of styling, rectangular frames are often chosen when you want structure—especially if you’re coming from softer, rounded frames and want a more defined look. And for the Rincon II, the suggested face-shape fit (oval and round) is the kind of guidance that can actually save you from a “looks off” purchase.

What stands out in everyday use

Polarized sunglasses can change your day without you noticing it right away—until you take them off. On bright mornings, glare off water, pavement, or glossy surfaces can make you squint or feel like your eyes are working harder. With polarized lenses, that glare reduction tends to feel more like the scene becomes easier to read.

A practical micro-scenario: imagine you’re driving toward a low sun, and the dashboard reflection is distracting. Polarization often helps cut down that harsh bounce of light. It’s not magic in every lighting condition, but it’s one of those features that makes a visible difference when sun intensity ramps up.

Limitations to keep in mind

A polarized lens is helpful, but it doesn’t replace the need for proper sun coverage. If you’re expecting wraparound coverage that blocks light from the sides, the “rectangular full-rim” look may feel more straightforward than ultra-wrap styles.

Also, frame shape matters. This model is rectangular by design, so if you strongly prefer round or heavily curved frames, you might find the Rincon II’s silhouette a little too structured for your taste—even if the polarization is what you came for.

Who it’s for (and who should skip it)

This is a solid pick if you want polarized lenses and a rectangular, full-rim frame shape that’s especially suited (per the provided guidance) to oval or round face shapes. It makes sense if you care about glare reduction for everyday outdoor time, travel, or any bright, high-reflectivity environment.

It may not be the best match if you’re unsure about rectangular proportions for your specific face shape, or if you’re chasing a very side-covering, sporty wrap style. In those cases, it can be smarter to prioritize frame shape coverage first and polarizing second.

Is it worth it?

The Costa Del Mar Men’s Rincon II is worth considering if polarized sunglasses are your priority and you like a more defined rectangular look. The combination of polarization plus a structured full-rim frame generally fits people who want their eyewear to do real work in bright conditions—not just look good indoors.

You might want to pass if you’re sensitive to frame shape or you need a more wraparound, side-blocking style. Also, if you don’t match up with the recommended face-shape guidance (oval/round), you may end up thinking it’s “close,” but not quite right.

Mini FAQ

How do I know if a rectangular frame will suit me?

Start by checking the face-shape guidance provided: rectangular styles tend to look best on oval and round faces. If you’re unsure, compare your current frames—if they’re softer and rounder, you may notice a stronger contrast with rectangular.

What does polarized help with day to day?

Polarized lenses are designed to reduce glare. That can make bright scenes feel easier to look at, especially when reflections are intense.

Are the listed dimensions important?

Yes. The 64/11/134 numbers are there to help you judge fit. If you’ve ever had sunglasses that sat too wide or too narrow, the dimensions are a useful check.

Does polarization replace sunglasses with full coverage?

Not entirely. Polarization helps with glare, but it doesn’t automatically guarantee side-light blocking. If coverage is a major concern, pay attention to the frame shape and how it sits.
