When synthetic fabrics go into the laundry, they shed small pieces of plastic called microfibers, creating thousands of particles that end up polluting the oceans and waterways—swimsuits and swimming trunks are particularly bad for the environment, as they are made with materials like nylon, polyester and spandex for their stretchy and moisture-wicking properties. Outerknown sets itself apart with an innovative pair of swim shorts called Woolaroo, which are made from 100% merino wool, which the brand refers to as "nature's original performance fiber."

The merino wool Woolaroo swim trunks are all-natural, renewable, temperature-regulating, naturally odor-resistant and breathable, as well as quick-drying and UV protective. Unlike microfiber pollutants, the biodegradable fiber used to create these swim shorts helps to return nutrients to the earth and the fiber will naturally decompose in months.
