The Fjallraven Kanken Rainbow 16L Backpack is pretty much begging to be taken on a class trip, to a music festival, or simply down to the farmer's market. This handy little pack features a durable, water-resistant construction in case of spills, and is accented with colorful straps that make the bag pop when the sun comes out. Carry some snacks and a change of clothing in the main compartment, and you've still got room in the side pockets for a water bottle, plus a zippered front stash for your phone, wallet, and keys. The bag even comes with a seat pad for laying out on the grass when you need a break from wandering venues or food stands.
