DESCRIPTION RATINGS & REVIEWS PRESCRIPTION GUIDE

The Maui Jim KUPALE MJ639 Sunglasses bring retro style into sharp focus. These bold rectangle frames feature a chunky profile and the brand's vintage logo embossed in high relief on the temples—a design detail that nods to Maui Jim's Hawaiian heritage while delivering a fresh, modern look. Available in five finishes including Shiny Black and Shiny Orange, the KUPALE makes a statement on city streets or sunny coastlines.

MauiPure LT: Lightweight Clarity That Performs

The KUPALE is built with MauiPure LT lens material, Maui Jim's thinnest and most lightweight lens technology. These lenses deliver optical clarity comparable to glass while weighing a fraction of traditional glass, and they pack exceptional impact and scratch resistance for active lifestyles. The result? Sunglasses you can wear all day without fatigue, backed by the durability to handle whatever your day throws at them.

Every pair features Maui Jim's patented PolarizedPlus2 technology—a multi-layer lens system that eliminates 99.9% of glare, blocks 100% of harmful UVA and UVB rays, and enhances color so ocean water appears deeper blue. The lenses also include anti-reflective coating on the backside to eliminate bounce-back glare, plus oleophobic and hydrophobic treatments that repel water, oil, and smudges for easier cleaning.

Fit, Features & Prescription-Ready

The KUPALE measures 55mm lens width, 17mm bridge, and 145mm temple length—a large unisex fit that works well for round and oval face shapes, where the angular rectangle frame adds definition and balance. The full-rim nylon frame is lightweight yet durable, with a saddle bridge and traditional pin hinges. The 4-base curve provides comfortable wrap without distortion.

These sunglasses are prescription-ready. Most Maui Jim frames can be fitted with prescription lenses through an authorized eye care professional, so you can enjoy PolarizedPlus2 clarity with your exact vision correction. Maui Jim backs every pair with a two-year warranty against defects in materials and workmanship, plus repair services for as long as parts remain available.

Frequently Asked Questions

Are the Maui Jim KUPALE MJ639 sunglasses prescription-ready?

Yes, the KUPALE MJ639 can be fitted with prescription lenses. Most Maui Jim sunglasses are available with prescription lenses in both single vision and progressive options, and must be dispensed through an authorized eye care professional's office since prescription lenses are considered a medical device.

What is MauiPure LT lens material and how does it compare to glass?

MauiPure LT is Maui Jim's thinnest, lightest, and most lightweight lens material that delivers optics nearly as clear as SuperThin Glass with exceptional impact and scratch resistance. It's 27% thinner than standard MauiPure and combines the optical clarity of glass with ultra-lightweight construction, making it ideal for all-day wear and active lifestyles.

What does PolarizedPlus2 technology do?

PolarizedPlus2 is Maui Jim's patented lens technology that eliminates 99.9% of glare, blocks 100% of harmful UV rays, and enhances color through a blend of three rare earth elements. The technology includes anti-reflective coating on the backside of lenses, plus oleophobic and hydrophobic treatments that repel water and oil for easier cleaning.

What face shapes work best with rectangle sunglasses like the KUPALE?

Rectangle sunglasses like the KUPALE work particularly well for round and oval face shapes. The angular frame adds definition and balances softer, curved facial features. Oval faces are naturally versatile and the rectangle shape highlights their inherent balance, while round faces benefit from the angularity that helps balance curved features.

How should I clean and care for my Maui Jim KUPALE sunglasses?

Rinse your sunglasses daily in lukewarm water and use mild liquid dish soap (free of additives) to wash each lens surface. Dry with the included cleaning cloth and avoid paper products, tissues with lotions, or abrasive cleaners. Follow the "on your face or in the case" rule to protect them when not wearing them, and avoid excessive heat like car dashboards.

What warranty does Maui Jim offer on the KUPALE sunglasses?

Maui Jim offers a two-year limited warranty from the date of purchase against defects in materials and workmanship when purchased from an authorized reseller. The warranty covers manufacturing defects and Maui Jim will repair or replace defective sunglasses, though it does not cover normal wear, lens scratching, or accidental breakage. Repair services are available for as long as parts remain in the collection.

Maui Jim KUPALE MJ639 vs. BREAKWALL MJ422 vs. BANYANS MJ412

All three models deliver Maui Jim's renowned PolarizedPlus2 lens technology with 99.9% glare elimination and 100% UV protection, but they serve different style preferences and budgets.

The KUPALE MJ639 stands out with its retro-inspired design featuring a bold, chunky profile and vintage logo in high relief. At $153, it's the most affordable option while offering MauiPure LT—Maui Jim's lightest, thinnest lens material. The playful color palette (including Shiny Orange and Petrol Blue) makes it ideal for customers who want sunglasses that double as a fashion statement. The rectangle shape works particularly well for round or oval faces seeking angular definition.

The BREAKWALL MJ422 ($138-$183) offers a more traditional rectangle aesthetic with broader mainstream appeal. It's the lowest-priced option and delivers the same core PolarizedPlus2 benefits, making it a solid choice for customers prioritizing value and classic styling over distinctive design details. However, it lacks the KUPALE's unique retro character and embossed branding.

The BANYANS MJ412 ($191-$222) takes a sportier approach with wrap-style coverage that's better suited for high-activity outdoor pursuits like fishing, boating, or trail running. The increased side protection and athletic aesthetic come at a higher price point, and while excellent for performance, the BANYANS may feel too sporty for everyday casual wear where the KUPALE excels.

Our recommendation: Choose the KUPALE MJ639 if you want distinctive retro style with modern performance at an accessible price. Its bold profile and vintage details make it the most fashion-forward option, while MauiPure LT lenses keep it lightweight for all-day comfort. The KUPALE delivers premium Maui Jim optics with personality that stands out from the crowd.
