Forget practical: backpacks are all grown up. Bright block colours and quilted leather are replacing tomboyish neutrals and nylon, perhaps inspired by the graffitied Chanel version that appeared on the SS14 catwalk. Also, you can thank Belgian fashion designer Raf Simons (he's also artistic director at Christian Dior, FYI) for leading the way with his slick collab with Eastpak: trust us, one look and you'll be a plush-backpack convert.
