The Raen Kostin sunglasses draw inspiration from the much-adored Froyd optical frame in the Raen collection, resulting in a style that's both timeless and adaptable. With the cava design, they reinvent the classic silhouette, adding meticulous elements like the distinct keyhole nose bridge, split bar tack hardware, and the unique reversed temple design. Crafted from recycled bio acetate, these sunglasses are handcrafted using Mazzucchelli's M49 Bio Acetate, a material that embodies both biodegradability and compostability, showcasing our commitment to sustainability and exceptional craftsmanship.

About the Brand


Raen began as the brainchild of Justin Heit and his Californian crew in 2008. Raen existed as a means of creating a product that was different to what was in the industry at the time. The brand provides a point of difference and a unique and innovative approach to design.

Drawing inspiration from architecture, photography and furniture, Raen continues to create a classic aesthetic with superior workmanship and modern design. Appealing to a wide demographic, Raen Optics offer a classically styled array of sunglasses many of which are hand crafted from acetate and designed to look equally as good as a sunglass or prescription optical.

Manufacturer's Warranty


Raen sunglasses are covered by a 12-month warranty against manufacturer faults. For more information regarding returns and warranties, visit our help & FAQ's page.
