100% cotton. Button closure. Zip fly. Belt loops. Front zip pockets. Back welt pockets. Adjustable belt.At first glance, Dries Van Noten’s Penson Pants might look like your average pair of trousers. You should know, though, that the disruptive Belgian designer doesn’t exactly adhere to industry standards. To elevate this particular style, Dries implements a long silver zipper at the side pockets, while also adding an adjustable belt to the mix. The pants are designed to be worn high on the waist, and they boast wide legs that make them ideal for pairing with boots and chunky dad sneakers.
