These swimwear may look like straight from the 40's but they are made of a hyper modern swimsuit fabric. Meaning it dries fast, are stretchy and made for swimming.
They are best washed by rinsed in cold water. You can use a washing machine at 30° without softener and hang to dry after. Hang to dry out from the suns reach.
All plastic based clothes have fiber break offs that leaks out in to our rivers and oceans. That is why we highly recommend all synthetic clothes to be washed in a Guppyfriend washing bag that stops micro plastics from getting loose.
