adidas zip fastening backpack. Boxing class in the am, after-work plans in the pm? This backpack combines spacious storage with a durable, smooth build, made even sturdier by the polyester lining. So it'll discreetly contain all your kit, with front and side zip pockets for things like your phone and ear buds. The air-mesh straps keep your workwear looking pristine well into the evening hours. Made in part with recycled content generated from production waste, eg. cutting scraps, and post-consumer household waste to avoid the larger environmental impact of producing virgin content. HH7069
