Krøyer Recycled Twill and Leather Backpack Black/Multi. The Krøyer backpack’s zip-closure interior features a padded sleeve large enough for a 15-inch laptop along with two slip pockets, two mesh zip pockets and a pen holder. A zippered through pocket on the back allows earbuds to extend through even when closed. The exterior also features easily accessible vertical and horizontal zip pockets. The twill material used on this bag is made from recyclable plastic.
