Gear: This duffel is a pack and a bag

Eagle Creek’s newest travel bag has all the advantages of big, roomy unstructured duffel and all the hands-free portability of a well-designed backpack.

That’s because the Systems Go Duffel Pack 60L is both. Used as a backpack, the 2 1/2 -pound, water-resistant bag benefits from a fully padded back panel and adjustable padded back strap, sternum strap, and hip belt.

Or you can tuck away the hip belt, detach the back straps and recombine them to create a single cross-body duffel strap.

Multiple zippered access points let you load from the front or the top, and there’s a lockable zippered bottom compartment with an internal zippered divider to create two packing spaces.

A zippered side compartment and internal computer sleeve aid organizing.

Eagle Creek Systems Go Duffel Pack 60L in red or black costs $160.
