Buying Advice
The best ultralight hiking backpack is not always the lightest one. Torso fit, back-panel comfort, pocket layout, and load transfer matter just as much as the headline weight.
Choose a more mainstream lightweight pack if comfort and versatility matter most. Choose a more specialized ultralight model if aggressive weight savings are the top priority and you are comfortable with the tradeoffs.
