The reviewer says Knack designed the bag around airline size requirements, allowing compliant carrying regardless of which carry mode the traveler chooses. The expanded packing area accommodates about a week of travel while remaining within most airline carry-on size requirements, according to the review. The reviewer found switching between duffel and backpack modes simple, using metal D-rings and a straightforward clip mechanism on the shoulder straps.
The shoulder straps tuck into a dedicated back-panel zipper pocket, enabling quick conversion to duffel carry while traveling. An internal water-bottle pocket keeps the bottle separated from contaminants and preserves the bag's cleaner exterior profile, the reviewer notes.
