The problem with using plastic in clothing is once it is thrown away it will not decompose in a landfill.I am a now former employee of Walmart. I had concerns about what they were doing with it, too. They recycle the plastics and use it to make their own plastics in their Great Value brand, and use it to make the associates' vests/polos. They also get discounted vendor prices for supplying plastics to brands like No Boundaries, that make their clothing with recycled plastics.
