What Type of Backpack is best?

OK, I've leaving to go on a 9-12 month trip around the world in about 6
months or whenever I get enough dinero. I got money for Christmas and
am going to buy a backpack but I don't know which one to get. I'm going
to be on a tight budget for the trip so I'm not gonna buy many
souvenirs and whatnot and will survive on 2-3 outfits. But I'm probably
gonna need atleast for a while a winter jacket (I think). A Couple
questions:

Internal Frame vs External Frame?
What Size?
Are Layers better than a winter jacket? (will that save space?)
Brand names? Model names?

Thanks everbody!

The best answer to this question is, honestly: Whichever one fits you
best.

| Internal Frame vs External Frame?

Internal frames are more popular these days, and lower profile.
However, external frames allow you to more easily strap stuff to the pack.

| What Size?

Depends on what you are taking. If you are going with mates, borrow one
of their packs, and see if you can get everything you are taking into it.
If not, go bigger.

| Are Layers better than a winter jacket? (will that save space?)

This really depends on what climates you are going to. Some places get
very cold, and several thin layers just won't cut it.

| Brand names? Model names?

I took an Arc'Teryx Khamsin 52 (4400 cu/i) on my last 3 month trip, and
it worked out great ... very comfortable. Probably could easily do 9 months
with it.
