If someone is reviewing backpacks, zippers are also critical. I bought what I thought was a decent hiking pack from what we Americans call an "Army surplus store" for what seemed a good price. After a couple months two of the zippers had failed and I ended up throwing it away because I don't think there was any reasonable way to fix them. They were not YKK zippers (which I leared about) and I guess that was my mistake for not realizing that would be the point of failure. The old phrase "The poor man always pays twice." is in play here. Brands do have meaning, because they provide some assurance that the product meets some level of quality.
