Flat Top Sunglasses

Retro flat top sunglasses, custom manufactured for your brand — OEM/ODM from 300 pieces.

Flat Top Sunglasses

Flat top sunglasses are defined by their straight upper brow line, a retro detail that gives the frame a confident, vintage character. The style sits between browline and aviator aesthetics and has found a loyal following in menswear and heritage fashion, making it a distinctive but sellable addition for brands and distributors. The clean horizontal brow also makes it a favorite for logo placement and subtle branding.

The flat top line must be perfectly level and clean, since any unevenness is immediately visible across the brow. SunDefeat manufactures flat top sunglasses in acetate and metal combinations, with the flat brow accented through color blocking, metal trim or contrasting rims. Polarized, mirror and gradient lens options are available, all with UV400 protection as standard. Spring hinges can be fitted for added comfort and durability.

We reproduce your flat top designs from samples or drawings through OEM and develop original versions through ODM. Custom logos, temple printing, cases and packaging finish the line under your brand. Production runs at a 300-piece MOQ and four-week lead time, with pre-production samples approved before the full run begins, so every batch matches the sample you sign off on.
