Costa Mainsail XL Sunglasses

The Costa Mainsail XL Sunglasses are built for anglers and outdoorsmen who need extra-large coverage with dependable all-day comfort. Based on a best-selling hybrid frame design, the Mainsail XL expands the fit for broader faces while maintaining the performance features Costa is known for.

Equipped with polarized 580P polycarbonate lenses, the Mainsail XL reduces glare, enhances visual clarity, and helps minimize eye fatigue during long hours on the water. Micro side shields and hooding help block peripheral light and protect against wind and spray, while vented nose pads improve airflow to help reduce fogging. Retainer-ready temple tips provide added security when conditions get rough.

Ideal for bass fishing, offshore trips, boating, travel, and everyday outdoor wear, the Mainsail XL is designed for those who need larger fitment without sacrificing optical performance or comfort.
