Heh..Eric, I don't mean to be rude and trust me when I say I would behave this way with my best friends, my mom, and you, but I have to say, you really make me laugh.
I think it's funny how you come up with these definitions that you use and then expect everyone to understand them and agree with them. A "real backpack"..What in the world are you talking about? I saw how earlier you were talking about the fact that the items could be carried in cargo pants (they can't) so maybe you mean since a backpack isn't necessary (it is) that the backpack one wears isn't a backpack. I really don't even know. You are seriously splitting hairs here.
I mean first you say that SULers aren't backpacking and then you say they aren't wearing backpacks. They ARE wearing backpacks. How can you argue this? What kind of justifications go on in your head? I truly mean no offense, but I think the only one that has to "get real" is you. Seriously, your arguments are terrible. I'm sorry to say this. This forum is usually really passive aggressive, and I'm the last one to ever get involved, but if you want to make a claim, make it well. So far you aren't making any valid points. I'm sorry, but saying "that is not a backpack" when by every definition in the world it is, doesn't work.
I'm truly trying to figure out your thought process. Is it not a backpack because it can't handle enough supplies to last out there for a week (or some other amount of time) without resupply?
So please, Make a case for yourself that goes beyond "because I say so."
And to address the last point, SULers DO have a name that distinguishes them. They are called Super Ultra Light hikers. You've been using this term from the start. It is clear what it means right? Can we not agree that SUL hiker is a term to describe what you are talking about?
P.S. "I think its better to define what is not a real backpack, rather than to try and define what is a real backpack. I think a 5 lb SUL load, plus a little food and water, is not a load that equals a real backpack load."
Eric, you can't define what something is by saying what it is not. That is what 6 year olds do. Can you imagine a game show that goes like this. "Behind this door is a prize that will change your life! We're going to give you a clue and then you'll have 5 minutes to guess what it is. It is NOT a horse."
Would anyone win? No, they wouldn't. They won't win because you can't define what something IS, by saying what it is NOT. That's how things work. It's very simple. You define what something is, by giving characteristics of what it is. So I'll help you:
"My name is Eric and I believe a backpack is a tool that functions using (insert shoulder straps, fabric, whaever goes into the physical characteristics of a backpack) to carry a load that is greater then a base load of 5 lbs plus a little food and water."
That's how defining something works. Note that this is just restating what you said, but with a little more detail, perhaps a load range that it should carry or some other characteristics you think of, you can come up with an actual definition of a backpack in your eyes.
