For just over 7 months of travelling I have a 45+8 litre bag. I don't plan on taking much, a few pairs of socks, boxer shorts, 5 or so tshirts, 2 pairs of shorts, flipflops some jeans and a fleece.
I can always buy a tshirt or 2 if needed.
I also have a 20 litre day bag, should i bother taking this as it will obviously be a bit of a hassle carrying 2 bags around, especially when trekking in hot rainy weather. On the other hand if i go on day trips then having stuff like sun cream and water in a bag would be good. I could always put anything like this in a plastic bag and hang it off my belt or something if my main bag isnt with me.
I am going to the following places
thailand - 3 months
oz - 2 months
nz - 1 month
fiji - 16 days
LA (and surrounding) - 10 days
NY - 8 days
Yes, it is a good idea to take the daybag. But the daybag should be foldable. I found a very lightweight one in a drugstore once, it zips down to about the size of my palm and I take it with me whereever I go.
something like a thick plastic bag with draw string and cord to go over your shoulder then? (rather than the 20litre berghaus freeflow bag that i can live 3 or 4 days out of)
I was more thinking about a cheap jansport bag or the Jack Wolfskin F-light. Something to hold your guidebook, jacket, map and snacks while you are sightseeing. Foam padding in the back instead of any kind of fancy carrying system. Or maybe something like this:
Has the advantage that makes it harder for thieves to get at your things if you carry it in front.

I did some more digging. I have not found the one I use anywhere. But if you do a lot of trekking and hiking I would go for taking the Vaude Rock Mini along.
