It’s easily one of the top three questions asked of RTW travelers (right after “Why are you doing this?” and “How are you financing this little venture?”): What does one pack for a year-long trip?
So here’s your answer. I’m still editing this list— I’m sure I’ll ditch some stuff (like clothes) and toss in a few odds/ends, but this is pretty much it. Travelers, feel free to offer your suggestions.

What am I missing? Too much or not enough of something?

Looks good. I think the only thing I would add would be some flip-flops for hostel showers.
Yeah, I figure the sandals can serve double duty as shower shoes. If not, cheap flip-flops can be had the world over.
