Celebrate Plastic Free July with Solid State Clothing’s 100% Cotton T-Shirts! Synthetic textiles, such as polyester and nylon, are the biggest contributor to microplastics in the ocean, accounting for 35% of the total volume. This is because just one load of synthetic clothing in a washing machine can produce several million microplastics. And if you’ve forgotten, the main ingredients of plastic are crude oil and fossil gas. Our t-shirts come from the Earth and can be composted back into the ground! #plasticfreejuly #plasticfree #nosynthetics #naturalfibers #cotton #dirttoshirt
