For an accessory that will work hard in your day-to-day life, look to this crossbody-cum-backpack from Balenciaga. Made in Italy from recycled black nylon, it has two zipped compartments – the main one of which houses a slip pocket to keep your keys. Designed for one-shoulder carry, it's perfect for slinging over the label's logo-printed T-shirts for an on-brand look.
