When
you travel, your backpack will become your home from which
you live. It will either make your trip easier and pleasant
or it will be a cause of frustration and pain, or both. Choose
your backpack after thorough research and many, many different
fittings. It is definitely worth the effort.
When traveling abroad, if you plan on doing a lot of moving around, avoid hand-held luggage and opt for a backpack. Your backpack should be light, durable and comfortable. Look for a 'bombproof' pack because it's going take a lot of abuse. Look for tough fabrics like pack-cloth or Cordura (especially in high-wear areas). Go with a reputable name-brand pack to ensure quality (hopefully). A name-brand pack will probably have some sort of warranty feature as well. Keep the colors subtle and 'easy on the eyes'... avoid hot pink and other disgusting colors. Aim to fit into the crowds as much as possible rather than stand out.
Your backpack is definitely one item that you do not want to try and save money on in exchange for poorer quality. You will be dependent on your pack, and any problems with it -- and there will be more if you buy a low-quality pack -- will directly impact your traveling experience. Spend good money on a good pack and feel confident that it will perform for you when you most need it to.
Internal
vs. External Frames
Older-style backpacks consisted of an external aluminum frame
to help the pack keep its shape. The pack cloth material would
then be 'hung' from within this frame. This was the only way
to help distribute loads within the pack. External frame packs
are very bulky and cumbersome to carry through crowds or on
busses. They are also relatively fragile, as the main 'skeleton'
of the pack is exposed to impact damage (such as while being
loaded and unloaded on an airplane). They have too many exposed
bars and straps and don't fit well on luggage racks on most
trains. Needless to say, this is not the backpack of choice
for most travelers, including myself.
Most modern backpacks have an internal frame. Internal frame packs have of a number of flat aluminum rods that are strategically placed within the pack to help the pack keep its shape. The main rods go from the top to the bottom of the pack and rest close to the wearer's back (with padding in-between of course). These rods can be bent slightly to conform to the contours of the wearer's back as well.
The overall shape of internal frame packs is tall and narrow, perfect for walking in crowds. The shape of the pack is generally maintained by what ever is in the pack. If it's half full, it can be cinched up and made even smaller. Internal packs are often built for serious hiking. They have fully padded back support, very wide waist belts to take most of the weight of the backpack off of the shoulder straps, and fully padded shoulder straps for added comfort. This style of pack is without a doubt the best choice for budget travel.
Top
loaders vs. Front loaders (convertibles)
Among the internal frame packs, there are two additional styles
to choose from. The first is the top-loading pack (TL). This
is primarily a large backpack with a small opening at the
top, closed with a cinch string and covered by a pocket flap.
The other style is a front-loading pack, often called a 'convertible'.
On this pack, the entire front of the pack unzips to expose
the inside in its entirety.
TLs are by far the more durable of the backpack styles. They offer more protection from the elements (like rain), tend to ride better on your back, and are usually narrower, fitting very closely to your body. Plus, because the main compartment doesn't rely on a large zipper, you don't have to worry about zipper problems like you would a convertible pack. TLs are the first choice of hikers and mountaineers for these reasons.
Although
TLs are usually more durable and have better support systems,
TLs make finding items in your bag somewhat difficult. You
usually have to pull most of your stuff
out to get to what's at the bottom. This is also a safety
concern because there may be someone watching you pull out
your camera, binoculars, shoes, etc while trying to get at
something at the bottom.
TL styles also usually have straps hanging out everywhere. If these straps get caught on a conveyor belt at the airport, the 'baggage bashers' will simply cut the strap to keep everything flowing smoothly. If you do use a TL, wrap and tuck the loose straps under each other to avoid this hassle.

Convertible
packs are designed specifically for traveling. With convertible
backpacks, the front panel zips open completely, so everything
stays organized and is easily accessible without unpacking
each time you need
something. You can also zip the shoulder
and hip straps away in a compartment when you check it in
at the airport.
Disadvantages to this style of backpack are that they are less weather resistant and the zippers may burst on you. Look for compression straps to take some of the stress off of the zippers. Travel packs are designed to have the civilized look of a soft suitcase. Because these packs are designed primarily as luggage, they tend to have a relatively less supportive suspension system than TLs. Walking for long periods or on uneven terrain will be less than pleasant while wearing a convertible pack.
Buying
Your Pack
When you go to purchase your pack, try it on and let the sales
person adjust the straps, pads and internal frame for you
to fit your body size. A good store will have weight bags
that you can put into your pack and walk around the store
with to simulate loads. Check out the quality of the suspension
system. The suspension systems of modern packs are designed
to transfer most of their weight to your hips, reducing back
strain. The waist belt should allow you to put most of the
weight on your hips and the straps should be wide and have
plenty of padding for comfort. Play with the adjustments to
fine-tune the fit. If a pack doesn't feel right now, it won't
feel right after several hours of walking around.
Fit is perhaps the most important factor to consider when choosing a backpack for a couple of reasons. First, backpacks come in different lengths depending on the length of a person's torso (upper body). Second, the larger the pack, obviously the more that can be carried in it. The volume of a pack's interior is usually measured in liters or cubic inches. If you are an ultra-light traveler, take a small pack. It's easier to walk in crowds and on trains with a smaller pack. If you run out of room, you should be able to strap extra stuff to the outside of your packs. I prefer to take a larger pack and keep everything inside for ease of use and organization. However, when you have the extra room in your pack, you will more than likely be tempted to fill it up.
Take a day-pack with you. You can either buy a separate one or just buy a travel backpack that has a detachable one that zips onto the outside. Carry your daypack on the plane to keep your toiletries, travel guide, cards, etc in. When you arrive at your destination, just put it into your large pack (or zip it on if you have a travel pack). When you arrive, you can use your day-pack for daily outings while you store your large pack at your hostel or the local train station. Daypacks also come in handy when you have collected too much junk and your large backpack is full. You can wear your day-pack on your stomach like a baby holder.
