Questions
Is a 40 L backpack always carry-on size?
Not always. Carry-on rules are based on external dimensions and vary by airline, so check the bag's dimensions rather than its liter rating.
Casual Daypack Backpacks
A casual daypack is the main backpacks decision. The Osprey Daylite Plus is the pick for everyday carry, and the Herschel or Patagonia options above suit style-led or lighter use.
