In many ways, I have to be a bit contrarian to this view that categories don’t mean anything. Talking about UltraLight gear (or SUL/XUL) means understanding what Ultralight means. For example, a 5 pound tent is hardly UL. Yet people assume that lightweight is close enough to UL to count and join in discussions anyway. Sometimes they are learning, sometimes just because they want to hear themselves talk.
The items used in UL also have a place in any pack..A light is needed. A tent is needed. A pack is needed, And so on. Without a definition of items that will make UL, we end up simply philosophizing about these items, ie, is it necessary, is it useful, is it wanted or needed, can it be built lighter, can it be built more durable or simply is it light enough? Is this the name of the game now? Simply carrying things you want and talking about the good and bad?
There is nothing wrong with having a 6 pound base weight and carrying a 30 pound pack. I do similar to this for most two or three trips. Food, fuel, water, simply make up the majority of my load. If we didn’t discuss UL in terms of base weight, it would become difficult to think in systems. After all, it is rather hard to throw around a 30pond pack in the same manner I carry 2night, sub-10 pound pack. But, base weight is only another metric. No different from Ryan’s computation above. A bit tounge in cheek, but equally valid.
No, without a clear definition of what ultralight packing means, it is difficult to talk of such things. On the trail, it means nothing…you are comfortable or you are not.
In last week’s heat wave, I was out hiking and didn’t use my jacket or sleeping bag. UL philosophy would have me drop these from my kit because I DIDN’T need them. I carried a spare set of batteries for my Steripen. I didn’t need them. But, I surely would have liked them if the temps were 40F and I needed a drink.
Anyway, packing is always contingent on conditions. Climbing mountains at 2 miles per day is a LOT different from hiking over flatter terrain at 22 miles per day. In both cases, I carry UL gear, but the gear WILL be different. (And, no, I don’t carry a 6 pound tent.)
