Prada's signature nylon pieces have been given a sustainable update in recent seasons — they're made from 'Re-Nylon' using recycled materials; like purified plastic trash collected from the ocean; fishing nets; and textile waste fibers. These track pants have a relaxed fit with a high-cut elasticized drawstring waistband. Pair them with the [matching bra top](https://www.modaoperandi.com/women/p/prada/re-nylon-bra-top/510664).
