Swim Trunks vs Swim Shorts: What’s the Real Difference?

What are swim trunks, exactly?

Swim trunks are typically shorter, looser-fitting bottoms that have been the go-to for beachgoers for decades. Think of those classic holiday shorts your dad probably wore.

Most trunks come with that built-in mesh lining we all know (and few of us love). While it’s meant to provide support, it often causes more discomfort than confidence — bunching, itching and stretching out.

Trunks serve a single purpose: swimming. And once you’re out of the water, you're usually counting down the minutes until you can change.

What about swim shorts?

Now imagine something different. A pair of shorts that feels good from the moment you put them on. Not just for a swim, but for the whole day.

That’s the difference with quality swim shorts. They’re designed to move with you, on the sand, in the water, at the café, or anywhere else your day takes you.

Take our Alyssa Mid and Grace Mini styles. They’re made for real bodies and everyday routines, with lengths and fits that match your comfort zone.

How do they compare on comfort and style?

Trunks are often lightweight, but they lack structure and rarely offer lasting support.

Swim shorts deliver a more considered fit. Ours, for example, are crafted from premium recycled nylon, meaning they support without pinching, stay put without riding up, and feel comfortable all day long.

How do they compare on function?

Let’s really simplify this: trunks do the basics. Swim shorts do more. Think:

• Surfing without wardrobe malfunctions
• Beach yoga without constant adjusting
• Walking from beach to brunch without changing
• Lounging, stretching, paddling, or whatever else your day brings

The real difference? Trunks are swimwear. Swim shorts are everything-wear.
