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 produces up to 30% lower carbon emissions than virgin polyester. Nike diverts an average of 1 billion plastic bottles annually from landfill and waterways.

  • Best training shorts

    AndrewC87817412 - 04 Jul 2024

    Please make more colorways! Fits well and looks nice for all my workouts and wearing casually.

  • Why is the Drawstring so long?

    KurtisH343371718 - 31 Dec 2024

    4/5 stars. They’re extremely comfortable and fit well. The only reason they aren’t a 5/5 is because the drawstring is extremely long. If I were to tighten them completely the draw string comes out 2+ feet on both sides. That’s my only complaint about them. Unsure if my pair was defective or not.

  • Not a fan

    Loved the prior version. The 3.0 fabric is weirdly coarse.
