Belt bags, waist packs, bum bags... whatever you call them, they're taking over our weekend wardrobe this season and given how practical they are, we couldn't be happier. This black leather version zips open to reveal a single compartment for all your essentials. The strap is detachable and fully adjustable (between 20.5cm/8in - 58cm/23in) - perfect to cinch it to your frame. Bag measures 14cm/5.5in in height, width across the middle is 25cm/10in and base width is 5cm/2in.
