10 Stylish Backpacks That'll Make Traveling a Million Times Easier

Waterfly Crossbody Sling Backpack ($21, originally $35)

Whether you're running around an amusement park or going on a hike, this sling bag has you covered. You can wear it on your front or back and it has an earphone hole, a water bottle holder, a mesh pocket for an umbrella, and a separate strap pocket. It's small, but fits a lot. Case in point: one shopper wrote that they could "fit a first aid kit and entire spray bottle with fan in the main compartment" and a "phone and sunglasses," in the smaller pocket.
