Built Where the Surf Is Serious
OTIS Eyewear was founded in 2000 on the rugged, surf-rich coast of West Australia, and every decision made since traces back to that origin. The Coastin Slim inherits that DNA: a performance wrap frame tuned for active use, wrapped around the only lens material OTIS will put in its eyewear. No plastic lenses, no shortcuts.
Mineral Glass Lenses: Why It Matters
OTIS uses eco-friendly mineral glass in 100% of its eyewear, and the Coastin Slim is no exception. Mineral glass delivers optical clarity that polycarbonate cannot match, resisting scratches that would cloud a plastic lens over a season of regular use. The polarized filter cuts glare off water, wet pavement, and sand so you can read the wave face and the lineup without squinting. This is not an upgrade tier; it is the baseline OTIS has held since day one.
Neo-Grilamid Frame Construction
The Coastin Slim frame is built from Neo-Grilamid, a high-performance nylon material chosen for its combination of light weight, flexibility, and resistance to salt, sunscreen, and UV degradation. The wrap profile keeps the frame close to the face for coverage when the wind picks up. Textured temple detailing visible on the frame is not decorative; it adds grip when the frame is wet. The fit is slim and streamlined, sitting closer to the face than a traditional sport wrap without sacrificing peripheral coverage.
Polarized Performance for Water and Beyond
Polarization is built into the mineral glass, not applied as a coating on the surface. That means the filter does not peel, degrade in salt water, or wear through the way surface-treated lenses can. On the water, polarized mineral glass resolves the depth and color beneath the surface that ordinary lenses turn into a mirror. Off the water, the same lens makes driving, cycling, and any outdoor activity with reflective surfaces significantly easier on the eyes.
The OTIS Commitment to Sustainability
Every pair of Otis Coastin Slim sunglasses uses eco-friendly mineral glass, a material that is inherently more sustainable than petroleum-derived polycarbonate. OTIS frames and lenses are designed to outlast synthetic alternatives, reducing the cycle of replacement that makes fast-fashion eyewear a recurring waste problem. Buying one pair that lasts is the most straightforward sustainability decision you can make in this category.
