A backpack for you, if you like traveling, on foot or by plane. It fits the standard restrictions on planes. Great capacity, Airback suspension system maintaining good backside ventilation, and compatibility with luggage organizers make this backpack fine choice for long trips.
If you fly often, but you prefer backpack as hand luggage instead of suitcase or flight bag. It fits the standard restrictions on planes, but can be easily extended by 12 liters after reaching the destination, holding things you can’t take on plane and need to be purchased later.
Elegant, sport-like appearance and high functionality — those are the traits of Messenger bag, dedicated for carrying documents, laptop, tablet, but also water bottle, keys, and traditional writing accessories.
