I bought two of these (should have gotten three!) for my teenagers to use for a two week trip around Tokyo and Hiroshima, Japan. I used a different hiking pack because it was bigger, but ended up packing it in a duffle bag for the flights there and back.
These packs are lightweight yet durable and structured enough to protect the contents. We had four planes, customs, five hotel changes, four bus rides and three train trips and they still look new except for the one little strap retention clip that snapped off on the first plane.
I used the Eagle Creek cubes and half-cubes to compress the clothes and organize the contents - perfect fit!
The side and top pockets were handy. Zippers are sturdy and easy sliding. The compression straps are great to keep the pack as small as possible and keep contents from shifting.
We had a number of hikes while changing hotels and these packs were comfortable even after hours of walking. The straps stowed securely for loading on the buses/train/plane and quickly pulled out to carry the load. The padded handles on the top and side are comfortable, even when heavy, offer options on carrying vertical or horizontal, and makes loading in the bus overhead or taxi trunk a breeze.
We carried 25-40 lbs in each easily. They can handle more but I didn't need the teens whining!
Highly recommend for summer camps and mixed-mode transportation camping/vacation use.
I still may get another!
