Deep, classic and quietly naval about the whole thing, the Polkadot – Midnight swim briefs from SULLIOS are for men who appreciate that some combinations simply never stop working.
Midnight navy with white polkadot is nautical heritage reimagined as modern premium swimwear. Wears as well on a superyacht as it does at the lido — though we'd recommend both, ideally in the same summer. You've earned it.
The 6cm side length delivers a modern, minimal fit — flattering, clean and designed to sit exactly where it should.
Crafted from premium recycled fabric, these men's designer swim briefs are built for both comfort and durability. They are chlorine resistant, quick drying and offer UV protection, making them ideal for beach clubs, swimming pools or long summer days in the sun.
Thoughtful details elevate the design, including a signature metal SULLIOS tag on the front, a silicone logo on the back, and a secure drawstring with plastic aglets for an adjustable fit. The briefs are also double lined for improved coverage and comfort.
…and did we mention, they're made from recycled fabric? Sustainable swimwear that looks good and does good.
