Best expandable backpack for commuters carrying large laptops and travel gear.
This is the ultimate workhorse for the over-packer who refuses to compromise on organization. Its expandable frame swallows gear for a weekend trip just as easily as a daily commute, though the sheer size means it can feel bulky on smaller frames.
