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. Ideal for the colder months, this puffer has a slightly oversized fit filled with lightweight, yet insulating down. The funnel neck and drawstring hem keep out winds, so it's not only stylish, but entirely practical.
