Super cozy! Nicely oversized…the rise (waistband to crotch) is super long which isn’t my favorite, but the pants are so comfortable and cozy that I’ll deal with that. If you’re getting the brown color, be aware it’s more mauve than brown. Other colors (my family bought every color) are true to the photos.

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.

Comfy fit

My wife loves them. She said they feel extra comfy.
Heerlijk warm en zacht, maar helaas niet de juiste fit voor mij.

Heerlijk warme en zachte broek en zit super comfortabel. De groene kleur is ook heel gaaf. Maar, ondanks mijn maatje S, zag ik er uit als een tientonner. Helaas retour dus.
