Microfibres are a type of microplastic released when we wash synthetic or semi-synthetic textiles (which make up more than 60% of clothing everwhere). Full disclosure: This means that washing your MARY YOUNG garments can release microplastic particles. The good news is that there are ways to reduce the number of particles being released! Handwashing your garments in cold water or using a shorter washing cycle is a great option. Using a filter (like this one) is also effective, however it may not be the most accessible option – other alternatives include The Cora Ball or The Guppy washing bag.
