Our take on the adidas Expandable Backpack

A small adidas daypack that unzips to expand when you need extra room, built with a waterproof shell and zippered main compartment. At 18 liters it starts compact for commuting or class and grows for a gym run or a light overnight. It suits people who want one bag that shifts between a daily carry and a weekend grab bag. Against fixed-size rivals it trades some structure for flexibility, and owners rate it highly for everyday use.
