Buyer's guide

Swim trunks you can wear without underwear.

21 reviews on what the liner replaces and how it feels.

Wearing boxers under swim trunks is a symptom of bad liners. Tucann's compression liner is an inner short in its own right, cut and supported like athletic underwear, so the trunk is worn on its own. 21 reviews raise the underwear question directly and the answer is consistent: nothing underneath, no chafe, proper support.

In their words

Customer photo from Amir J.
I wish the lining was tighter, especially on the 3" shorts (I also have a pair of the 5"). I worry about exposure on the 3", and unfortunately feel inclined to wear secondary underwear.

Great briefs, high-quality, typically wear a 34 and sized up to a XL and fits perfect. Tuscan products are all our high-quality and look great.

Very well made! My husband liked that the built in underwear actually offers support. The zippered pockets are helpful. Length is perfect.

These shorts are super comfortable. The built-in underwear doesn't slide into your behind like other brands. And the quality is very high.

Most comfortable boardies have ever tried on. Love the underneath material prevents use of boxers or underwear underneath boardies. Very quick drying and look and feel amazing

I love these trunks. As a "commando" guy, I hated the inside shorts, so I cut them out & now I love these trunks! I wish Tucann offered a no liner option.

I bought this swimsuit for my son who is 17. He would always wear underwear under his bathing suit to avoid chafing. He no longer has to do that thank...

I cut the liner out. My buddy that wears underwear under his trunks liked the liner, but to me it was too much material.

Frequently asked questions

Is it supportive enough?
Yes. It is a compression short, not a loose brief. Reviews from runners and swimmers confirm it holds.
Can you wear them all day without changing?
Yes, dry or wet. The liner is soft knit fabric and dries with the shell. Everyday wear is a whole category of reviews on this site.
What if I prefer to wear my own briefs?
You can, but the liner is fitted, so it will feel like a double layer. Most customers stop after the first day.
