REI posted a great minimalist packing list in the 18L Flash pack (I love mine.)
I smugly smiled, easily tossing my lighter-than-light 18-liter REI Flash Pack into the overhead compartment of my flight from Barcelona to Lisbon. There was none of the usual huffing and puffing, no last-minute hopes that my luggage would fit. And, if I really needed to, I knew I could shove it under the seat in front of me.
