This refined wayfarer style takes its name from a surfing trick, so you know it's going to look chill.A tail slide is part of a surfing maneuver where you purposely make your fins lose their grip and your board slides across the lip of the curl. Maui Jim's Tail Slide Polarized Sunglasses won't help you with that trick, but they will protect your eyes and improve your view on the water or at the beach so you can see someone else pull it off. Their PolarizedPlus2 lens technology goes beyond shielding your eyes from glare and harmful UV to reveal and enhance the colors that define your world. With SuperThin Glass lenses you get Maui Jim's crispest optics and the best scratch and solvent resistance. Lightweight nylon frames with adjustable wire tips are durable, resist corrosion and can be adjusted for a custom fit. Nonslip, embedded rubber nose pads are included for comfort and to help keep them on your face. Although, if you want to be extra sure they don't end up falling off at an inopportune moment (like in the middle of the ocean or in the middle of securing that primo spot next to the pool), a neoprene retainer or leash (sold separately) is inexpensive insurance.Lens TintBlue Hawaii – a blue flash mirror coating is applied to the outside surface of the PolarizedPlus2 Neutral Gray lens to reduce the amount of light that passes through, eliminate glare and boost color.
