This is the default size for the Adventure Pack. Plenty of space for tons of gear without having to expand the pack out. Perfect for travel! Should you need to fit under the seat, simply remove the frame and the height will drop down to about 20".

45 liters of gear brings the Adventure Pack to about half-way full. At this size the pack has started to fill out and up slightly and candidly there is not much visual difference between the Adventure setup at 45 liters vs. 35. At this size the Adventure Pack will need to go in the overhead bins.

The Adventure Pack can hold an incredible amount of gear and as you can see, grow out instead of getting wide on the side. Even at this size, you can still get a jacket stuffed into the front ATLAS stretch pocket. Getting the pack onto a plane at this size may involve a lengthy conversation at the gate.
