It'll feel less like kicking him out of the house if you help him load up The North Face Terra 55 Backpack with a sleeping bag, tent, food, and warm clothes before you boot him out the door. The Terra holds plenty of gear for a weekend scout trip or a camping expedition with his best friend's family, and carries comfortably with an adjustable Optifit suspension that'll let the pack grow with him. There's plenty of padding and ventilation in the back panel and waist belt, too, along with a bottom sleeping bag compartment for easy access.
