How This Was Made

  • The recycled polyester used in Nike products begins as recycled plastic bottles, which are cleaned, shredded into flakes and converted into pellets. From there, the pellets are spun into new, high-quality yarn used in our products, delivering peak performance with a lower impact on the environment.
  • In addition to reducing waste, recycled polyester reduces carbon emissions by up to 30% compared to virgin polyester. Nike diverts an average of 1 billion plastic bottles annually from landfills and waterways.

I use these while weightlifting and running. They perform great and are so cute! I'm surprised they only have 4.1 stars as I've tried many other brands and none come close.
