What Is a Sunga? The Men's Brazilian Swim Brief, Explained
If you've spent time on a beach in Rio, you've seen the sunga. It's what Brazilian men actually wear in the water — and once you understand it, you'll wonder why you ever hid under a pair of board shorts.
What is a sunga?
A sunga (pronounced soon-gah) is the Brazilian men's swim brief: a swimsuit with a fitted, low-to-mid rise and clean side coverage. The word is Brazilian Portuguese, and the style was popularized on the beaches of Rio de Janeiro. Think of it as the middle ground between a speedo and swim trunks — more coverage and structure than a racing brief, far sleeker and more flattering than baggy shorts.
The sunga isn't about showing off. It's about looking put-together and moving freely — the confidence of a man who's comfortable in his own skin.
Sunga vs. speedo vs. trunks
- Speedo (racing brief): minimal, built for competitive swimming. Great in the pool, less so for the beach.
- Swim trunks / board shorts: maximum coverage, but bulky, slow to dry, and shapeless.
- Sunga (Brazilian swim brief): the balance — a tailored, quick-dry fit that flatters your frame and works from the water to the beach bar.

The three Caio cuts
- Classic Cut: balanced, square-cut coverage. The timeless Brazilian sunga — the easiest place to start if you're new to the style.
- Slim Cut: a lower-rise, streamlined silhouette with a seamless front. Sleeker lines, fewer tan lines.
- Bikini Cut: our lowest-rise, minimal-coverage cut for maximum sun and a bold statement.
"Can I pull this off?"
Almost everyone asks this first — and the honest answer is yes. A sunga flatters more body types than trunks do, because a tailored fit reads as confidence, while baggy shorts just add bulk. Start with the Classic Cut, go one size up for the full sunga look, and wear it like you mean it. Most guys come back for a second pair.
How to care for your sunga
Rinse in cool water after each wear, hand wash separately, and hang to dry. Skip the dryer, bleach, and fabric softener. Caio sungas are built with premium quick-dry fabric, reinforced stitching, and UV/chlorine resistance to hold color and shape season after season.
Frequently asked questions
Is a sunga the same as a speedo?
Not exactly. Speedo is a brand name that became the word for any swim brief, like Q-tips for cotton swabs. What people usually mean is the racing brief: narrow and cut tight for laps. A sunga has a wider, square side and fuller coverage, made to wear all day: the beach, the beach bar, the gym pool.
What size sunga should I buy?
Caio fits true to size. For the full sunga look, with a little room the way Brazilians wear them, go one size up. See the size chart on each product page.
Are sungas good for bigger guys?
Yes. A well-fitted sunga flatters most body types — a tailored fit reads better than baggy shorts. The Classic Cut offers the most balanced coverage.
