Choosing men's swimwear starts with the shape you like and how much coverage you want. UPRO's swimwear collection includes swim briefs and close-fitting square-cut trunks. Here is how to compare the two before choosing a colour and size.
Swim briefs: a higher leg opening
Swim briefs have a shorter side and leave more of the upper thigh uncovered than square-cut trunks. Compare the front, side and back views of a particular style: the waistband and back coverage can differ between designs.

Square-cut trunks: more upper-thigh coverage
Square-cut trunks extend farther down the upper thigh, with a straighter leg opening. The styles discussed here are close-fitting swim trunks, rather than loose board shorts. Choose between the two cuts based on the silhouette and coverage you prefer.

Four UPRO styles, side by side
Compare two brief designs and two square-cut designs, then choose the pattern you prefer.

Sailor Stripe Swim Brief
Black-and-white horizontal stripes in a brief cut. Compare this regular stripe pattern with the botanical print below.

Bird of Paradise Print Swim Brief
A blue-and-orange botanical print with contrasting graphic details. Choose between this print and Sailor Stripe while keeping the brief silhouette.

American Stripe Square-Cut Swim Trunks
Yellow pinstripes in a square-cut shape, with UPRO SPEED lettering at the back. Check the rear-view photos for that detail.

Abstract Print Swim Trunks
A blue abstract print in a square-cut shape. Compare it with the yellow striped trunks when choosing a pattern with more upper-thigh coverage.
What to check in the product photos
- Front and side: compare the waistband height and leg opening.
- Back: check the coverage of the individual style.
- Selected colour: use the colour selector and corresponding product image to confirm your choice.
- Details: read the listed material information rather than assuming every swim style uses the same fabric.
Choose the size for the specific style
Start with the fit and size guide, then use the size chart on your chosen product page. Compare your own measurements with that chart; a size label alone is not enough. If you are between sizes or unsure how to interpret a measurement, contact UPRO before ordering.
Planning a pool or beach trip?
Choose your preferred cut first, then colour and size. Each item is sold individually, so different pieces can be added to the same cart without buying a preset pack. Orders ship from Hangzhou, China. Check the shipping policy and the delivery options for your destination, allowing time before a planned trip.
