These sunglasses feature a refined rectangular frame that best fits medium- to large-sized faces.Red Sand Beach has sands that are a deep red-black color that really pops next to the clear Hawaiian waters on Kaihalulu Bay. Just as striking are Maui Jim's Red Sands Polarized Sunglasses. Their PolarizedPlus2 lens technology quickly goes beyond shielding your eyes from glare and harmful UV rays to revealing and enhancing the colors that define where you live and play. Utilizing MauiPure lenses, Maui Jim's most popular non-glass lens material, you get optics almost as crisp as glass yet they're ultra lightweight and offer excellent scratch and shatter resistance. And their lightweight frames are made of injected nylon with a high-gloss finish that really makes their colors pop. You'll find the adjustable, nonslip nose pads are comfortable and help keep your sunglasses on your face. Although, if you want to be extra sure they don't end up falling off at an inopportune moment (like when snapping photos of the dolphins escorting your boat or beachcombing on one of the only red sand beaches in the world), a neoprene retainer or leash (sold separately) is inexpensive insurance.Lens TintsHCL Bronze – this tint is versatile in changing conditions and provides excellent contrast.
