Silverfin Sport: Sunglasses for the Bottom of the River

Field notes

The product is organized around recovery rather than ordinary eyewear styling: the frame and lens are designed to remain together at the surface, while the inner temple colour is intended to become conspicuous only after immersion. The page also assigns every pair a number and asks customers to identify that number when claiming the first-year replacement promise. Future colourways are tied to seasons, regattas, and club editions, with the stated policy that sold-out versions will not return.
