Marni are really on top of things at the moment. Their last two collections have been bang-on; nice and casual, infusing a streetwear aesthetic with their signature minimalism – as have their accessories, the latest of which is this leather backpack. Weighing in at approximately 16 litres, the forest-green pack is made from supple lamb leather with navy and grey canvas trims. It’s got all the compartments and flaps you could ask for in a day pack and is fully lined in nylon. Padded straps and a drawstring fastening finish it off nicely. The Marni Leather Backpack is available through Mr Porter.
