Most of the time, we talk about the experience of wearing underwear. But what about once you’re ready to retire them? The hard truth is not so comfortable.

In fact, approximately 11 million pounds of underwear end up in landfills every day. Most underwear is made of synthetic fibers, like nylon and elastic, that take hundreds of years to decompose. In the process, they contribute to synthetic microfiber pollution, which is a huge—and growing—problem.

In one study of aquatic samples in both freshwater and ocean water, about 90% of the debris found was from microfibers. Another found that 85% of debris on shorelines worldwide was from microfibers. What’s more, this pollution may bioaccumulate as it moves up the food chain. 

At Uwila Warrior, we’re determined to be part of the solution, not the problem. That’s why we are pleased to announce new Better Briefs: In partnership with CiCLO®, we have developed a revolutionary new way to make underwear—with the same look, feel, and quality you love—that is better for the planet.

The (not-so-) secret? CiCLO® technology, a patented and scientifically proven solution that allows synthetic textiles to behave more like natural fibers in a landfill environment, without compromising on durability.

How CiCLO® works

CiCLO® technology is a nature-based solution to help mitigate fugitive synthetic microfiber pollution caused by textiles. CiCLO® technology is applied to fibers at the start of the manufacturing process, allowing synthetic materials to break down naturally in end-of-life environments—which means that your discarded undies will break down faster and into smaller increments, resulting in less microfiber waste.

Thanks to this cutting-edge technology, your pieces will be just as stylish and soft as you expect from all Uwila Warrior. The CiCLO® technology will only affect how they behave once they are disposed of. You can find out more about CiCLO® technology at
