Sunski's Shoreline is a square aviator frame built from SuperLight, a proprietary recycled resin sourced from US landfill material, paired with a steel core and sculpted contact points for a stable, pressure-free fit. Polarized TAC lenses block 100% of UVA, UVB, and UV400 wavelengths and pass the FDA basic impact test, cutting glare on the water, on the trail, or in a sunny commute. The large-coverage frame fits most faces without pressure. Four colorways, each with its own lens character: Olive Amber, Spruce Slate, Tortoise Bronze, and Rust Slate. Backed by a lifetime warranty.
