Built for the Water, Made to Last
The Costa Del Mar Bloke is an extra-large performance sunglass designed for men who demand durability without sacrificing style. Whether you are on the water fishing, surfing, or simply living in the sun, the Bloke is engineered to stay on your face and keep your vision sharp all day long.
580G Polarized Glass Lenses
The Bloke is fitted with Costa's 580G lens technology, polarized glass ground to a Base 8 Decentered curve. The 580 spectrum lens blocks high-energy yellow light while enhancing reds, greens, and blues, delivering contrast and color accuracy that makes it easier to see into the water and track fish below the surface. Glass lenses provide superior scratch resistance and optical clarity compared to polycarbonate, making the 580G the choice for serious time on the water.
Bilateral Fusion Frame Construction
The Bloke frame uses Costa's bilateral fusion technology, a process that fuses two materials together into a single, chip-proof frame. The result is a finish that holds up to hard use, saltwater exposure, and daily wear without flaking, peeling, or chipping. The cam action pin hinges add a further layer of reliability, operating smoothly through thousands of open-and-close cycles without loosening.
Hydrolite Fit System
The nose and temple pads are made from Hydrolite, a proprietary material that grips more securely as it gets wet. Rather than slipping when you sweat or take spray, the Bloke holds its position on your face in rough conditions. The XL frame fits a broader face profile and provides generous coverage to block peripheral light and reduce glare from all angles.
Who the Bloke Is For
Costa built the Bloke for core anglers and water sports enthusiasts who need a sunglass that performs as hard as they do. The combination of polarized 580G glass, a chip-proof fused frame, secure wet-grip pads, and XL coverage makes it one of the most capable on-water sunglasses in the Costa lineup. It is available at Island Water Sports in South Florida, in store and online.
