A long weekend. A mid-week work trip. Our innovative ZERØGRAND 48-Hour Backpack handles both perfectly, eliminating the need for another carry-on. From the anatomically mapped shoulder straps to the lightweight, durable construction, it’s loaded with thoughtful details that keep you comfortable, organized, and in full flight. Plus it fits in both overheads and under the seat in front of you. The only thing it doesn’t do? Pack itself.
