The Maui Jim Twin Falls MJ417 sunglasses bring the spirit of Maui's secluded Ho'olawa Valley waterfalls to your everyday adventures. This modified rectangle wrap frame delivers full coverage without the bulk, fitting comfortably under baseball caps and wide-brim hats thanks to its low-profile design and rounded edges.
PolarizedPlus2 Technology: The Maui Jim Difference
Every pair features Maui Jim's patented PolarizedPlus2 lens technology—a multi-layer system that eliminates 99.9% of glare and blocks 100% of harmful UV rays. Unlike ordinary polarized sunglasses that simply darken your view, these lenses are infused with three rare earth elements that enhance red, green, and blue wavelengths, revealing colors as they truly are. The result is exceptional contrast, depth perception, and visual clarity that brings out fine details in every scene.
The Twin Falls uses MauiPure lens material, Maui Jim's most popular choice. It combines optics nearly as crisp as glass with ultra-lightweight construction and excellent scratch and shatter resistance. You get premium clarity without the weight—perfect for all-day wear whether you're driving, fishing, golfing, or teaching on the beach.
Choose Your Lens: HCL Bronze or Neutral Grey
The Rootbeer Fade frames pair with HCL Bronze lenses—a warm, high-contrast lens that works beautifully in variable conditions from overcast to full sun. The bronze tint enhances contrast and makes colors pop, ideal for everyday use. The Gloss Black Fade frames feature Neutral Grey lenses, Maui Jim's darkest option, perfect for bright, direct sunlight and sensitive eyes. Both lens colors include the brand's bi-gradient mirror treatment that reduces glare from above and below.
Lightweight Comfort That Lasts
The Grilamid frame is ultra-thin and remarkably light—so much so that wearers often forget they're wearing sunglasses. Adjustable Rabalon nose pads prevent slippage and customize the fit without leaving heavy indentations. The traditional pin hinges operate smoothly, and the rounded temple tips rest comfortably behind your ears without poking or pinching.
Available with bifocal reader powers (+1.50, +2.00, +2.50) discreetly integrated into the lower lens area, the Twin Falls eliminates the need to switch between sunglasses and reading glasses. The reader element is nearly undetectable from the outside. This frame is also prescription-ready for single vision and progressive lenses.
Customers consistently praise the exceptional comfort and all-day wearability of this lightweight design.
The Twin Falls suits oval, round, and heart-shaped faces. It's a unisex design that delivers versatile, lightweight coverage for active lifestyles and relaxed days alike. Includes Maui Jim case and cleaning cloth.

Frequently Asked Questions
Are the Maui Jim Twin Falls sunglasses available with prescription lenses?
Yes, the Twin Falls MJ417 is prescription-ready and can be fitted with single vision or progressive prescription lenses. Maui Jim also offers this model with bifocal reader powers in +1.50, +2.00, and +2.50 magnifications. The reader element is discreetly placed in the lower lens area and is nearly undetectable. For custom prescriptions beyond the standard reader powers, consult with an authorized Maui Jim optical professional.
What's the difference between HCL Bronze and Neutral Grey lenses on the Twin Falls?
HCL Bronze (High Contrast Lens) offers a warm tint that enhances contrast and works well in variable light conditions from overcast to full sun—it's excellent for everyday wear and makes colors more vibrant. Neutral Grey is Maui Jim's darkest lens, ideal for bright, direct sunlight and sensitive eyes. It provides true color perception and the highest light reduction. Bronze feels warmer and performs better in low light, while Neutral Grey excels in intense sun and reduces eye strain on bright days.
What is MauiPure lens material and how does it compare to glass?
MauiPure is Maui Jim's most popular lens material, combining optics almost as crisp as SuperThin Glass with ultra-lightweight construction at just one-third the weight of glass. It offers excellent scratch and shatter resistance, making it ideal for active lifestyles. The material is injection-molded for crisp optics and provides exceptional impact resistance while maintaining the visual clarity Maui Jim is known for. It's lighter and more durable than traditional polycarbonate while delivering near-glass optical quality.
Do the Twin Falls sunglasses fit comfortably under a hat or baseball cap?
Yes, the Twin Falls features a low-profile wrap design with rounded edges specifically engineered to fit comfortably under baseball caps and wide-brim hats. The frame sits close to the face without interfering with hat brims, and the adjustable nose pads allow you to customize the fit to prevent the frames from sitting on your cheeks, which helps avoid fogging. This makes them particularly popular for golf, fishing, and outdoor activities where hats are commonly worn.
What does PolarizedPlus2 technology do that regular polarized lenses don't?
PolarizedPlus2 goes beyond standard polarization by incorporating three rare earth elements into the lens that enhance red, green, and blue light wavelengths. This technology eliminates 99.9% of glare and 100% of UV rays while actually boosting color vibrancy and contrast—unlike ordinary polarized lenses that simply darken your view. Every lens includes anti-reflective coating on the back to eliminate bounce-back glare, plus oleophobic and hydrophobic treatments that repel water, oil, and fingerprints for easier cleaning.
How lightweight are the Twin Falls sunglasses?
The Twin Falls is exceptionally lightweight due to its ultra-thin Grilamid frame material and MauiPure lenses. Multiple customer reviews specifically mention the remarkable lightness, with some users noting they barely feel the sunglasses on their face during all-day wear. The Grilamid frame maintains strength and flexibility while staying ultra-thin, and the MauiPure lenses weigh just one-third of what glass lenses would weigh. The adjustable nose pads distribute weight evenly without creating pressure points or heavy indentations.

Maui Jim Twin Falls vs. Other Wrap Sunglasses
If you're considering the Twin Falls MJ417, you might also be looking at other Maui Jim wrap-style frames. Here's how they compare:
Twin Falls vs. Breakwall MJ422
Both frames offer the same PolarizedPlus2 technology and lightweight Grilamid construction, but the Twin Falls has a more established reputation for all-day comfort based on customer reviews. The Breakwall starts at a slightly lower price ($138 vs. $178) and offers similar wrap coverage that fits under hats. If budget is your primary concern, the Breakwall is worth considering. If proven comfort is paramount, the Twin Falls has more customer testimonials specifically praising its lightweight feel and adjustable nose pads.
Twin Falls vs. Lighthouse MJ423
The Lighthouse MJ423 ($153-$184) sits in a similar price range and offers comparable wrap coverage. Both frames feature the same lens technology and are available with reader and prescription options. The key difference comes down to frame geometry and how each fits your specific face shape. The Twin Falls is particularly noted for its rounded edges and low profile that work well under baseball caps, while the Lighthouse may have different temple length and bridge dimensions. Try both if possible to determine which contours to your face better.
Twin Falls vs. Banyans MJ412
The Banyans ($191-$222) is a step up in price but offers the same core technology: PolarizedPlus2 lenses, lightweight Grilamid frames, and wrap coverage. Both are available with readers and prescription lenses. The Twin Falls has more extensive customer feedback specifically highlighting exceptional comfort and the quality of the adjustable nose pads. Unless you prefer the specific styling of the Banyans, the Twin Falls delivers comparable performance at a better value.
Why Choose the Twin Falls?
The Twin Falls MJ417 stands out for its proven track record of all-day comfort, extensive positive customer reviews, and versatile lens options. It's particularly well-suited for active users who wear hats, need reader powers, or want a frame that disappears on the face. The combination of MauiPure lenses and ultra-thin Grilamid frames creates one of the lightest, most comfortable wrap sunglasses in the Maui Jim lineup—at a competitive price point.
