backpack, i ordered a charcoal one to start with. however, if i use it a bunch, i might get an indigo one, too (LOVE the color, but it's sold out for now). i'm thinking about a couple of these sash/belts to use with it The Sash | Shop American Apparel (adds a little color, y'know?), plus my trusty black icebreaker cami and shirt and maybe a couple other odds and ends to change it up or for when i inevitably spill something on myself.
i'll definitely post packing list/pics for each trip once it's closer to go time! each trip has a very different purpose and climate to work around, so the packing challenge is extra exciting!
