Small enough to serve as an airline carry-on and large enough to haul heavy textbooks around school the durable JanSport Air Vital Backpack is a companion you can count on whether traveling across the country or campus. A large main compartment holds a big stack of notebooks and manuals or a couple sets of clothes depending on your agenda. To carry the weight in comfort the Jansport Air Vital Backpack relies on unique shock absorbing AirLift™ shoulder straps to distribute the weight evenly. And to keep heavy contents from shifting back and forth as you walk up a trail or across an airport concourse side compression straps keep the load tight and riding close to the body. Whether commuting home from school via bus or flying home for the holidays the slip-in magazine stash sleeve comes in handy for those who like to pass their down time with some recreational reading.
