Given the weather here due to mountain terrain and elevation, it'd be hard to stay comfortable without a cold-weather sleeping bag. I can skip the tent as long as it doesn't rain though.
In like fashion, in New England mountains (especially the Whites) rain gear and some warm clothing is always needed. Add to this the extra bulk/weight that comes being well over 6' tall and wearing XL clothing.
Ultra-light gear is really expensive, especially considering the gear I already have is free to use.
It's the same with cycling components. With cycling, I made up spreadsheet and tracked component options on a gram and $ basis and, no kidding, calculated the gram/$ ratios of the various options. (If I were on CIS, I would be McGee) When you add into this the issue of durability, I'd rather stick with some older, well proven and durable things than toss/replace stuff. My Svea 123 is in this category. I have an old TNF pack purchased in '84 and used multiple times a year ever since. Yes, I've rebuilt parts of it, but it still works great.
My knife weighs 0.8 oz, and I rarely use even that. There just aren't many things in the natural outdoors that need cutting. It would be a different story if I was a hunter, or if winter camping (forget that!).
I lived and worked, hiking and backpacking, outdoors for many years (ten years staff at Philmont, twelve years as a professional archaeologist) and I've never encountered any cutting task outdoors that an Opinel couldn't accomplish easily.
Ditto on the Opinel. For winter ski tours (where fires are possible), folding saw and larger fixed blade are nice but really a luxury item, not a must have.
Dead wood is usually abundant; fire restrictions preclude campfires much of the year; and the best fires (easiest for cooking, easiest to no-trace when finished) are built with thin sticks that are easily broken by hand.
I would like to hear more on this. Do you use a twig stove? If so, what kind?
I know it's "impact elsewhere" not "no impact" but I still primarily rely on my stoves (Svea 123 or Trangia 25). A big part of this is the massive rates of traffic that we see in the Whites combined with the very limited places to roll out a sleeping bag. Most of our hiking terrain is very rough forest and once you get above the hardwoods into the boreal, forget about it. As a result, most camping ends up being localized at established (or quasi-established) camp sites. And with localized impact, wood over-harvesting can be a major issue.
