Each legging is made from around 25 recycled plastic bottles or plastic material collected from land and beaches all around the world. The process to make clothing from plastic bottles is as follows: The bottles are broken down into tiny flakes, those flakes are melted into pellets and then melted again. They are then filtered and spun into threads. Which becomes the material that your Firehart Legging is made of. Only 9% of the Earth’s plastic has been recycled, but companies like Firehart are committed to increasing the percentage that gets recycled, by using more recycled materials and fabrics.
