Great list Charlie! I noticed the word tampons in there. Have you considered a menstrual cup? I have had one for over over 15 years now and they are fantastic! I only had to buy tampons once in that time and that was because we drove 4 hours to a beach town and guess what came along? Argh. But yeah, I pair that with three pairs of Thinx underwear and I am set. I highly recommend them to anyone, but especially full-time travelers:)

PS. I am envious of your small backpack. We have way too much shit! It's time to downsize!
