The Broadbill II XL is an XL-sized, 8-base squared frame built for big and wide faces. These Costa Del Mar polarized fishing sunglasses for men pair an injected bio-resin frame with integrated hinges and a co-molded build for a secure, comfortable fit that stays put through long days on the water. The lenses do the heavy lifting. Costa 580 glass and polycarbonate options filter harsh yellow light at 580 nanometers to sharpen reds, greens and blues, cut blinding glare off the water and reveal detail and contrast you would otherwise miss. Every lens is polarized and blocks 100% of UVA and UVB rays, with superior clarity and scratch resistance whether you choose the ultra-clear 580G Lightwave Glass, with encapsulated mirrors that are 20% thinner and 22% lighter than average glass, or the lightweight, impact-resistant 580P polycarbonate with its scratch-resistant C-WALL bond. They are built for the way you actually fish. From bright open water offshore to sight fishing the flats and inshore, plus boating, paddling and everyday saltwater wear, they keep your vision locked in from sunup to sundown. The wide, wrap-friendly fit suits larger faces that smaller frames leave exposed. Part of Costa's performance collection, they are eligible for all manufacturer warranties and ship with a protective microbag and cleaning cloth. Costa was born on the water. In 1983, a group of avid fishermen in Daytona Beach, Florida could not find sunglasses tough enough for life in the salt, sun and glare, so they built their own. More than 40 years later the mission has not changed: make the best sunglasses on the planet for life's great adventures and protect the waters we love, from the flats to the open ocean. Every pair is engineered to help you See What's Out There. Click the Costa Del Mar link above the product title to shop the entire Costa Del Mar assortment.
