adidas Lifestyle Classic 3-Stripes Backpack Unisex Red IL5784

This is the coolest way to wear your 3-Stripes — curved around your backpack. This sturdy adidas bag has plenty of room for your daily gear, with a choice of side pockets for your water bottle. There are also two inner slip-in pockets to keep your keys and cards tucked away. And while this bag is all about curved lines, you won't be, because the ergonomic shoulder straps support your posture.
