Excerpted from the post "Gear List – 12 Month Round the World Trip" @ The Quest for Awesome:
You’re leaving the country for a year. What do you pack?
It took me 6 months to finish answering this question. Not only did people say I was crazy when I told them I’d be trying to do it with a 32 liter bag, they said it wasn’t possible. I ended up leaving the country with a 26 liter backpack [the Smart Alec].
Traveling as light as possible was the driving factor because of the freedom it allows (and partially just to see if I could do it). When a 26 L backpack is all I have:
There’s no need to check baggage
I look less like a tourist
I have higher mobility
I have lower dependency on having to find a spot to store/lockup my bag
