Chuck Sun | Brett Sunglasses

Yes. This is the major differentiating point of Brett Eyewear: the 304 stainless steel temples have been specifically designed to be ultra-thin and flexible, allowing them to easily slip under a helmet without creating pressure on the temples. Unlike classic lifestyle sunglasses whose thick temples quickly cause discomfort under the helmet, the Chuck Sun remain comfortable even on long rides. The large format also does not exceed the helmet opening on most Hedon, Bell, Shoei and standard open-face helmet models.

The Khaki / Silver colour offers a vintage military shade that integrates with scrambler, trail and roadster builds with natural dominants. The Crystal / Silver offers a refined transparency that enhances bright builds, neo-retro and minimalist café racers. The Grey / Copper combines cool grey and warm copper, in coherence with dark, bobber and assertive café racer builds. The choice mostly depends on your wardrobe and the visual universe of your motorcycle.

A polarized lens is fitted with a filter that eliminates light reflections from flat surfaces: wet roads, dry asphalt, car bonnets, windows, metallic surfaces. For the motorcyclist, this translates into a much better reading of the road, an accentuated contrast between shadow and light areas, and a significant reduction in visual fatigue over long distances. The Divel lenses used by Brett are high-end, guarantee faithful chromatic stability and provide complete protection against UVA and UVB rays.

Acetate is a cellulose-based material, considered the high-end reference in eyewear. It offers a depth of colour and tactile quality that injection-moulded plastic cannot match. Acetate is also more resistant to thermal deformation, more stable over time, and allows for complex finishes (marbled, transparent, gradient materials). It is the material used by the great French and Italian eyewear houses.

The Chuck Sun come in large format (lens size 57 mm). This format suits medium to wide faces and builds seeking an assertive visual presence. To check compatibility with your face, measure the width of your face between the temples: if it is greater than 135 mm, the large format is suitable. For a narrower face, Brett offers other models in medium or small format. The FCR Accessoires team can advise you in case of hesitation.

Each pair of Chuck Sun is delivered in its original Brett packaging: a rigid protective case for storage and transport, a microfibre travel pouch to clean the lenses daily, and a Brett-signed craft packaging. The Brett warranty applies according to the brand's terms.
