There are backpacks for a variety of use, but here I address the question from the title with the focus on packs for outdoor use, and this means hiking, mountaineering, and backpacking.

Regarding the torso size, the best hiking backpacks 65 liters plus for an X-small woman will have 13 inches (33 cm) torso length, there is nothing smaller on the market.

There are many reasons why you would want to have a framed backpack, and they are easily understandable. But there are also a few reasons why some people rather choose frameless packs.

I have seen the question from the title asked by some people, and have noticed a variety of very different answers that address completely different aspects of a pack. So the question may be ambiguous, and it is properly answered here.

When this is about hiking and backpacking backpacks, nowadays canvas backpacks are hard to find and they are not very popular. There are reasons for this.
