I traveled around Costa Rica for 5 months, going from hostels to farms all on public transportation. I am a small person, so I was a little worried how it would be to carry around 30 lbs+ on my back all the time, but this pack was actually easier to carry than the 20 L backpack I had. Packed light (only clothes, maybe some food) and without the top compartment, it was easy to keep on my lap durning crowded bus rides. It held up well when put in the storage compartment of the bus as well. I plan to use it on my trip through Patagonia as well. My only suggestion is to make sure to get sized for it before you order though!
