The Maui Jim KAIWI CHANNEL MJ840 Sunglasses are built for water sports enthusiasts who demand serious glare protection and optical clarity. Named after the challenging channel separating Oahu and Molokai, these wrap-style sunglasses deliver the performance you need whether you’re paddling, fishing, or simply enjoying time on the water.
The Kaiwi Channel features Maui Jim’s SuperThin Glass lenses—32% thinner and lighter than standard glass while providing the absolute crispest optics available. These lenses offer superior scratch and solvent resistance, essential for saltwater environments. The patented PolarizedPlus2 technology eliminates 99.9% of glare, blocks 100% of harmful UV rays, and enhances color with a blend of rare earth elements that boost reds, greens, and blues. Every lens includes anti-reflective coating, oleophobic treatment for water and oil resistance, and protection against high-energy visible (HEV) blue light.
“Optics are sensational. Polarized lenses are beyond belief.” — Tommy Bahama customer review
The triple-injected nylon frame construction provides durability without bulk. A saddle-style bridge with embedded rubber nose pads and non-slip temple tips ensure a secure, comfortable medium fit (62mm lens width, 16mm bridge, 123mm temple) even during active use. The 8-base curve wrap design blocks peripheral light and glare bouncing off the water at harsh angles. Spring hinges add flexibility and long-term durability. Available in four distinctive stripe patterns with matte finishes—Grey Black Stripe, Burgundy Stripe, Dark Brown Stripe, and Blue Black Stripe—each paired with performance lens tints including Neutral Grey for bright conditions, HCL Bronze for everyday versatility, Blue Hawaii mirror, and Hawaii Lava mirror.
The Kaiwi Channel is available with prescription lenses through authorized optical retailers. Maui Jim offers 96% of their sunglasses in prescription, using MauiBrilliant, Polycarbonate, or MauiEvolution lens materials to accommodate most prescriptions while maintaining PolarizedPlus2 benefits. These sunglasses are recommended by the Skin Cancer Foundation as an effective UV filter for the eyes and surrounding skin, and they’re saltwater-safe and corrosion-resistant—just rinse with filtered water after use.
