Francis, I'm getting a backpack, does this one from North Face make sense? I wish I could make more sense by telling you I need my backpack to be this and that, but nope, pretty much clueless. So overall, good or bad? Thanks!
There's the old saying, "If you don't know where you're going, any road will get you there."
Similarly, "If you don't know why you need a backpack, then any backpack will be fine."
In general, I advise getting lightweight backpacks (1 kg). I love what Gossamer Gear makes.
However, without knowing your specific needs, I can't advise you. It's like if someone asked you "Should I buy the Toyota Camry?"
If you don't know much, then I suggest saving money and getting a cheap, used one on eBay or Craigslist.org. After gaining experience, you'll understand your preferences and be able to buy the best backpack for you.
