A bum bag that transforms into a backpack and is made in part with recycled materials.

We love options, and this adidas by Stella McCartney bum bag is full of them. Because it's not just a bum bag. You can turn it into a backpack, depending on what you're up to that day. It's made from super-lightweight material, so whether it's strapped around your waist or hanging from your shoulders, it feels good. Made with a series of recycled materials, and at least 60% recycled content, this product represents just one of our solutions to help end plastic waste.
