You love the benefits of glass lenses super scratch-resistant but arent stoked on the weight heavy glasses kill your nose-bridge. Maui Jim made the Kapena Polarized Sunglasses with lenses that use a thin, light glass. This means you get durability and scratch resistance without the weight of normal glass. The polarized technology blocks glare and UV, manages blue light, and boosts colors so you wont have to squint when youre out on the water. Treatment on the lenses and frame holds up to saltwater exposure.
