I love these pants. As soon as I tried them on, they felt warm, cozy, and perfectly oversized. For reference, I’m a true medium in bottoms, 5’6” and 163 lbs. The only thing I noticed is that the rise from the waist to the crotch is longer than I expected so it feels very high waisted. I might be able to size down to a small, but I’m not sure it would work for me since I have a little bootayy. I’m worried a small might fit too closely and end up shorter at the ankles. Aside from the extra-long rise and how super high-waisted they are, the pants are extremely comfortable. I’m even considering ordering a small in another color just to compare the fit. Overall, they’re definitely worth it. I just wish the crotch wasn’t quite so long.

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.
