Our garments are special. They are supporting sustainable fashion, and the recycling process, by turning trash into treasure. The fabric we use is more resistant to chlorine and sunscreens than other fabrics but we still need to care for it to extend its lifespan and get the most out of it. We recommend a cold, gentle machine or hand washing in mild detergent to stay smelling fresh and to clean grubby adventurer marks. To keep playing in your Cosmo Crew swimwear, base layers and beach shorts longer, please rinse after each use and dry in the shade to avoid fading. Do not wring, soak or dry clean. Avoid contact with rough surfaces and keep away from puppies who like to chew.
