The Duke Sun belongs to the iconic Duke line by Brett Eyewear, the flagship model of the French brand. Inspired by speed enthusiasts and free spirits, the Duke features a retro style and sporty allure inspired by speed. A declaration of audacity, an invitation to venture off-road. This classic version of the Duke is characterised by an entirely acetate front, while The RX Duke offers an acetate front on a stainless steel frame. A stylistic choice for those who favour the warm and material rendering of a full acetate frame.
The main differentiating feature of The Duke Sun for motorcyclists: the paddle tip. Unlike classic rounded or curved tips, the paddle tip is flat and tapered, specifically designed to slip perfectly under a helmet without creating a pressure point behind the ear. It is the most accomplished solution for motorcyclists who spend long hours with their sunglasses under a helmet. No more discomfort after a few kilometres, no more difficulty putting on or removing the helmet between two stops.
The construction highlights premium acetate across the entire front face, bringing the depth of colour, tactile warmth and material richness characteristic of high-end full acetate frames. The 304 stainless steel temples, more corrosion-resistant than standard steels, structure the eyewear with finesse and guarantee mechanical durability over time despite the repeated handling of regular motorcycle use.
The Duke is the most direct expression of Brett's DNA: a racing café racer style, an assertive visual presence that does not go unnoticed, and a perfect integration in lifestyle universes with strong character. Particularly suited to café racer builds, sporty neo-retro builds and motorcycles with warm dominants.
The high-quality Divel polarized lenses reduce sun reflections on the road, wet asphalt and metallic surfaces. The polarizing filter improves contrast, reduces visual fatigue over long distances and allows for better reading of road relief. A real technical protection that goes beyond the aesthetic function of a simple pair of sunglasses.
Four colours are available depending on your build and wardrobe: Green / Copper for a sophisticated cool-warm contrast coherent with café racers, Black for total integration with dark builds and assertive café racers, Honey Tortoise / Silver for a timeless honey tortoiseshell, Crystal / Silver for a refined transparency suited to bright builds. Each pair is delivered in its rigid protective case with microfibre pouch and original Brett craft packaging.
For any question about colour choice, the difference with The RX Duke or compatibility with your helmet, the FCR Accessoires team is available by phone or email.

Discover Brett EyewearThe Duke Sun (classic version) is entirely in acetate, from the front to the material that structures the frame. The RX Duke Sun offers an acetate front on a stainless steel frame, which noticeably modifies the result: the front retains the depth of colour of acetate, but the stainless steel frame brings additional rigidity, more pronounced finesse and a slightly more technical visual presence. The choice between the two depends mainly on the style sought: full acetate (classic Duke) for a warm and material look, RX Duke for a more rigorous and architectural rendering.
The paddle tip refers to the flat and tapered shape at the end of the temples, as opposed to classic rounded or curved tips. On traditional sunglasses, the rounded tip creates a pressure point behind the ear when slipped under a helmet, especially after several hours of use. The paddle tip, thinner and more profiled, slips naturally between the head and the inside of the helmet without creating this pressure point. It is the most accomplished solution for motorcyclists who spend long hours with their sunglasses under a helmet.
The Green / Copper combines a deep green and warm copper for a sophisticated contrast, particularly successful on neo-retro and café racer builds with warm finishes. The Black provides total integration with dark builds and assertive café racers, with the warmth and depth characteristic of premium black acetate. The Honey Tortoise / Silver offers a timeless honey tortoiseshell, marbled and warm, that matches all outfits. The Crystal / Silver offers a refined transparency that enhances bright builds, neo-retro and minimalist café racers.
Yes, but with some clarifications. The Duke with paddle tips are designed to integrate particularly well with Hedon, Bell, Shoei, Arai jet and full-face helmets, and other premium brands. On full-face helmets with narrow openings or very tight modular helmets, use may be less fluid. The large format must also remain compatible with the front opening of your helmet. If in doubt, the FCR Accessoires team can advise you according to your helmet model.
Full acetate offers a different tactile and visual experience than acetate on a frame. The rendering is warmer, more organic, more material. The full acetate face better captures light in gradient and marbled colours (Honey Tortoise, Crystal). For those seeking the authenticity of traditional French and Italian eyewear, full acetate is the absolute reference. Conversely, acetate on a frame (RX Duke) brings technical rigidity and more pronounced finesse, perfect for a more contemporary rendering.
The Duke Sun comes in large format. This format is to be preferred for wide faces (width between temples greater than 140 mm) or for those who deliberately seek an assertive visual presence. For medium to narrow faces, this format may be too imposing. If you are unsure, measure the width of your face between the temples or contact the FCR Accessoires team for advice before purchase.
