A beloved item by many names, but this pair of ECO Endurance triangular swim briefs has quickly become one of our most popular pairs of swimwear for men. Made from Speedo's unique signature material Endurance Eco, consisting of 100% polyester (55% from recycled plastic bottles), you get the only available pair of briefs in sustainable materials that are also ultra chlorine-resistant. The design is kept simple and stylish with a side length of 7 cm, here in the color red. With these Eco Endurance triangular swim briefs, you can never go wrong - whether you're 15 or 45 years old, briefs are definitely back in fashion. They are used by many swimmers for lane swimming in the pool, but also at the beach. In addition to the undeniably great look they provide, they also offer the great advantage of giving you full freedom of movement and comfort. Something every man or young boy appreciates. Unlike all other triangular swim briefs on the market, these are even made from 55% recycled plastic bottles, which have subsequently been turned into a strong polyester thread. This also gives a good feeling in the body - and towards the environment. What's not to like?
