Ralph Sun | Brett Sunglasses

The three models belong to the same Bold collection by Brett Eyewear and share the same construction (thick acetate front of 5 to 10 mm on ultra-thin 304 stainless steel temples). They differ in their format and technical specifications. The Ralph Sun is the most compact with a 55 mm lens size and 145 mm temples, ideal for a balanced silhouette. The Tony Sun is in large format (56-16/150) with a more modern and wider posture. The Barry Sun is in medium format (55-19/150) with a wider bridge suited to strong noses, and offers photochromic lenses (versus polarized for Ralph and Tony).

The Bold collection by Brett Eyewear is based on a strong stylistic choice: the contrast between thickness and finesse. The front face is in thick acetate (5 to 10 mm), creating an assertive visual presence and an immediately recognisable graphic character. Conversely, the temples are ultra-thin in stainless steel, which preserves lightness and comfort. This play of volumes is what defines the Bold signature: audacity and elegance, with no compromise on either.

Yes. Despite the thick acetate front, the 304 stainless steel temples are ultra-thin and flexible, specifically designed to slip under a helmet without creating pressure on the temples. This is the Brett signature: maintaining comfort under a helmet even on models with an assertive front. The Ralph Sun slip easily under Hedon, Bell, Shoei helmets and most standard open-face or full-face helmets. The compact 145 mm temple length also makes it a model particularly suited to full-face helmets with narrower side openings.

Silver offers a timeless classic that matches all builds, from dark café racers to bright builds and chromed motorcycles. Gun olive green brings a vintage military touch coherent with scramblers, trails and off-road builds with natural dominants. Copper offers a warm and refined shade that particularly enhances neo-retro builds, café racers with warm finishes and motorcycles with dark liveries. The choice depends mainly on your wardrobe and the visual universe of your motorcycle.

The Ralph Sun is the most compact format of the Bold collection (lens size 55 mm, temples 145 mm). This format suits narrow to medium faces (width between temples between 130 and 140 mm) while retaining the strong graphic spirit of the Bold collection. The 17 mm bridge offers balanced comfort on most noses. For a wider face or a more assertive visual presence, the Tony Sun (large format) will be more suitable. The FCR Accessoires team can advise you in case of hesitation.

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.
