Pick a pack that suits your size and needs. In general, you should expect to pay somewhere between $150 and $250 for a good pack. (Cheaper ones might be exactly that, cheap, and more expensive ones aren't necessarily better.) A few things to look for while shopping around:

Frame

Backpacks generally come in two basic styles: external or internal frames. We strongly recommend internal parallel frames for Hostel Trekking. (External ones are more likely to get bent or broken by baggage conveyors, are more difficult to get on and off of trains and are less likely to fit in travel lockers.) Your best bet: a convertible travel pack that can be carried as either a backpack or hand-carried luggage.

Suspension system

This is what determines fit, and assures that most of the weight goes to your hips rather than your shoulders. ("Tell me about it," you're saying.) Seriously, a pack that fits properly - a wide and sturdy hip pad is key - should put almost no pressure on your shoulders. Try it on, secure the lumbar pad against your lower back, and adjust the hip pad so it rides comfortably on your hips. Then check to see that the shoulder straps are easily adjustable, well-padded and wide enough to be comfortable. Finally, put some weight inside and hike around the store for a few minutes to see how it feels. 

Fabric

Most packs are made of durable materials. "Denier" is a rating of the fabric's density - the higher the denier number, the more durable the cloth. Look for a rating of at least 1000, though you might want to go even higher.

Seams

The stitching should not be too close to the edge of the seam or the material so it won't come apart. Look for reinforced stress points, smaller stitches (so more per inch) and lock stitching (which won't unravel if a thread breaks) instead of chain stitching (which will).

Zippers and buckles

Zippers should be sturdy and slide smoothly. (Make sure the stitching is not too close to the zipper, or it might get in the way.) Carefully check the buckles on the waist and shoulder straps for strength and ease. Make sure that the zippers lock into place.

Handle

If you're considering a convertible pack, look for extra-heavy reinforced stitching and a comfortable grip.

Other features

If you're the organized sort - not a bad idea when on the road - then a lot of pockets and compartments will help you keep your stuff sorted. You might even consider a pack that has a zipper along the side so you can get at all your things; top-loading packs aren't great when what you need is at the bottom.
