I travel internationally as a medevac flight nurse on a medically configured jet. I am gone for 8-20 days at a time away from home. For many years I have used this and other Osprey bags exclusively, including the Manta, Elroy, and Sojourn. This bag is expandable, has multiple pockets to store my electronics, toiletries, shoes, medical gear, flight suits, and personal clothing. This has become my go to bag as I live out of it over 240 days a year. The size is perfect as a carry-on, the handle has never failed, the material is strong and durable, the wheels are tough as nails, and it looks great. The zip off backpack is great for day excursions, and carries quite a bit as well. I have used the bag as a backpack on rough terrain, and the suspension system is comfortable. And it can be removed to make room for other items.I've seen baggage handlers throw this bag around and it just keeps working. Best money I've ever spent. I am trying to give a well rounded review, but I haven't found any negative aspects to this bag. Bonus: Peace of mind with the any bag any era any problem warranty. You will not be disappointed.
