Deuter Utilion 30L Backpack

I bought this pack specifically for air travel, and it worked perfectly. It fits well under airplane seats, which made boarding and accessing my things really easy. I especially appreciated the zippered compartment that gave me quick access to my laptop without having to dig through the whole bag. The side pocket is a bit small for larger water bottles, but it holds smaller bottles or soft flasks just fine. Overall, a well-designed and convenient travel companion!
