The Caio Classic is a timeless Brazilian swim brief designed for balanced coverage, premium comfort, and a clean, confident fit.
This solid collection is made in Brazil using premium Brazilian fabric, chosen for its smooth, silky feel and more substantial weight. Compared to our lighter printed collections, these solids offer a richer hand feel and a more elevated, timeless finish.
The Classic cut is ideal for men who want a versatile Brazilian fit — refined, easy to wear, and flattering without trying too hard. It offers a balanced silhouette that works just as well for beach days and poolside moments as it does for resort wear and warm-weather travel.

Let customers speak for us
from 106 reviewsThe fabric is sturdy and reinforced in all the right areas keeping the fit from sagging. A beautiful fit!
Great swim suit
Great product !
I already got 4 sungas (speedos) and one of the knitted shorts and I am obsessed! The classic ones are the perfect Brazilian style cut, and the slim ones are so sexy! I have two of each. The shorts are so cool and perfect for a pool party and beach day. Got a lot of compliments! Thanks Caio!!
Great color, pattern, cut and fit. Would buy from again.
Amazing material and fit!
Love Caio. Its the only swimsuit that fits me prefectly. I’m so so happy I found this company.
Great cut and fit. Recommend!
Perfect fit, vibrant color as seen, and well made. Love it!
Great high-cut fit, looks just like the pics. Well made bikini-style suit.
Great quality and fit.
Flattering fit - very cool
Awesome colours - good fit
Fits perfecty - Brazilian Classic
Such a winning brief from CAIO. They really seem on top of their game here with this latest bikini cut. It is spot on - I love the smaller sides, they make for such a nice, trim and sexy fit, perfect for serious lap swimming or for just lounging about. They are supremely comfortable and ooze real quality and I love the full lining. If you’re looking for one of the best swim briefs on the market you’ve come to the right place. They are so good that I have already treated myself to both the Celestial Azure and Stellar Ash. And intend to buy the Nova Frost and the Starwood as well. I love eco nature of the construction and manufacture too. A really good message to share. Such a great brand!

Three Brazilian cuts, one honest question: how much do you want to show? Same color, same fabric — the only thing that changes is the coverage.

Bikini
The lowest cut we make. Cleanest line, most skin, zero apology.

Classic
The timeless sunga. Easy to wear, cut close enough to still turn heads.
