River Sunglasses - Black
Click to learn more ↘
Handcrafted with care, the River frame combines timeless influences with craftsmanship and fit that allows for lifelong wear. A true Monokel Eyewear staple with black frames handcrafted from organic and biodegradable acetate, black 100% UV protective Carl Zeiss Vision CR39 lenses.
Acetate is derived from plant-based materials like wood pulp, so we like it better than petroleum-based plastics for structured items like eyewear and jewelry - with bonus points when its biodegradable. The manufacturing process is key to ensure responsible wood sourcing, water use, and chemical disposal.
Made in China.
- Material 1: 100% Acetate
