Reebok teams up with Victoria Beckham this season to create a capsule of fashion-forward activewear - and this black backpack is a staple accessory from the Casual. Big enough to fit all of your essentials – and with room for more – it’s made using sturdy recycled polyester and features multiple storage compartments for optimal practicality. Its unstructured, slouchy build pairs well with any effortless look and it features adjustable straps for comfy wear also.
