Men's swim trunks for the pool and beach: offers from sellers

Updated 20 October 2026

Pool and beach need different trunks

Beach shorts and training trunks for the pool are made of different fabrics. Chlorinated water quickly “eats” ordinary nylon with elastane: the fabric goes dull, stretches and becomes see-through. For regular swimming look for chlorine-resistant fabric, usually polyester or polyester with elastane, which keeps its shape even after a hundred sessions.

For the beach you can pick quick-drying swim shorts. But for lap swimming many pools require close-fitting styles, so check your pool's rules in advance.

After the pool, don't leave wet trunks in your bag: the chlorine keeps working. Rinse them in fresh water, don't wring them out, and don't dry them on a heater or in direct sun, because heat destroys elastane. That way one pair lasts much longer, which changes the real price a lot.

One more thing to know: many trunks look the same from outside, but the seams and the inner lining differ. For long training sessions choose flat seams that don't rub and a drawcord or waistband that holds firmly through starts and turns.

The cut depends on the purpose

• Briefs – the classic sports model for swimming and competitions, with minimal water resistance;
• Boxers and jammers – longer, covering the thighs; jammers are chosen for training and races;
• Swim shorts – looser, for the beach and leisure, with an inner mesh lining;

What to put in your request

• Cut – briefs, boxers, jammers, swim shorts;
• Size – S/M/L or a number, and better still your waist and hip measurements;
• Purpose – pool, competitions, beach;
• Brand – for example Speedo or Arena, or any;
• Fabric – chlorine-resistant, quick-drying;
• Colour – plain without prints, or the opposite;
• Delivery city and budget – for example, courier delivery to your door.

Example: “I'm looking for men's swim boxers for the pool, size M (waist 82 cm), chlorine-resistant fabric, navy blue with no prints, preferably Speedo or Arena. Courier delivery to Manila, budget up to ₱1,100.”

How to compare offers

Check the fabric content on the label and in the photos. Ask whether the item is original or a replica if you want a particular brand, and whether you can return it if the size is wrong. Size charts differ between brands, so go by measurements in centimetres, not by the letter.

On BlaBlaPrice sellers send offers in the chat themselves, see their place among competitors and improve their terms. You get ready prices, the offer that gives the best value is shown first, and reviews are next to it. Your number stays hidden. You can read how it works on the “How it works” page.

Common mistakes

People use beach shorts for training and end up with stretched fabric by the end of the season. They go only by the letter size.
