Tell them to get their own bags.
It is never a good idea to bring a big bag when you're hanging out with your friends. Whoever brings the biggest bag is in charge of carrying everything anyone else doesn't want to carry—it's like a rule. One minute you're toting a cute bag, and the next, you're lugging around three cameras, two water bottles, sunglasses, and someone's flask all jammed into your bulging bag. The petite Billabong Lil Dude Backpack gives you room to carry your essentials without turning you into the group's pack mule.
