Costa Del Mar Mainsail XL Matte Gray Smoke Blue Mirror 580P Sunglasses Men's 59

The Costa Mainsail XL in Matte Gray Smoke with Blue Mirror 580P Polarized Lenses offers oversized lens coverage and performance‑oriented features in a stylish, modern frame. With its large 59mm lens width, long 146mm temples, and a generous frame width of 143.9mm, this model gives wide‑ranging protection while maintaining a “narrow fit” profile for those seeking a more streamlined temple spread. The 580P polarized polycarbonate lenses deliver excellent glare reduction, full UV protection, and optical clarity suited for marine, outdoor, and everyday use. Enhanced with micro side‑shields and hooding to control stray light, vented nose pads for breathability, and retainer‑ready temple tips, the Mainsail XL is built for serious wear. With its injected nylon construction it balances durability and comfort, making it an ideal choice for those wanting premium performance with a refined fit.
