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 ordered my usual size Medium and unfortunately they fit bigger than all of my other Nike flex shorts in that size. I thought there must have been a quality control issue… However, after receiving my second pair and measuring up they are 2 inches bigger.

Best shorts ever

Only had these a week. Purchased these for running in the summer. Perfect so light and cool you don’t know their there. Ideal for the gym just right for squats and lunges so good I don’t wear any other shorts. Will have to buy more pairs. Have only had these a week so can’t really say how durable they are yet.
