“It seems like so many folks show lower base weights including things I wouldn’t need like fat air pads or chairs. Looking for why, I come up with:
—They can carry frameless packs at much higher pack weights and no hip belt
—They go no-stove
—They don’t get cold.”
Which is why trying to use someone else’s list is not a good idea!
“My clothing setup wasn’t really on my radar screen, though, so it is helpful that you draw attention to that. I guess that is where I “pack my fears” as we all typically do. I never heard of down pants for hiking in cool conditions. Hardly heard of them at all except maybe for something skiers and mountaineers use. But would it be too warm for hiking? I don’t have any other long pants on my current list (except for the rain pants)—just the skirt that I wear the wool leggings underneath if it’s too chilly or windy.”
No, sorry, not down pants for hiking. I had assumed the long underwear was for sleeping/campwear. Many people do use them for backpacking, but almost never while moving. Andrew Skurka suggest bringing down pants if temps are going to be below 35 F or so.
“Think in terms of how many people just bring shorts and leggings, except that shorts and pants give me seam chafe so I switched to the skirt. Then if it rains or gets too cold even for that, on go the rain pants”
If that is the case, also interesting to check out knee warmers for warmer weather where you just want something to keep the knees warm in a breeze or under rain pants:

“Even with no rain in the forecast I never trust it not to rain.”
Absolutely agree. I was not suggesting to leave the rain gear behind(especially since you have a super light option). But there is a difference between expecting it to rain a lot and be damp and cool the rest of the time versus expecting it to rain briefly or not at all and be warm and dry the rest of the time. In the latter case, a lightweight rain jacket might be sufficient, for the former you’d want a full suit with good coverage and materials, a fleece/nano air layer for under the rain jacket, long underwear or pants under the rain pants, rainmits and dry sleep clothes.
“But yes, if the forecast is warm and dry I would probably leave the long sleeve wool baselayer shirt out”
The reasons to bring sleep clothes are either for prolonged wet, damp weather, or as extra warmth for camp and sleeping. In case of the latter, wool base layers are simply heavy for the amount of warmth they provide, so leaving them behind and adding (some of) that weight back as down fill, will get you more bang for your ounce.
“I do have a couple of somewhat lighter sleeping bags I could substitute I have to add 10-15 degrees at least, to any bag rating.”
Agreed, sleeping bag ratings are only an idea. You need to bring what’s warm enough for YOU. I simply meant that with warmer clothes, you might be able to get away with a lighter bag. Also, that in warmer weather you certainly would. I sleep cold too, but when it’s 60F inside my tent I don’t need a warm bag ;-)
“The MB vest looks interesting” I have never used it, and there are many other ultralight down vests too. It was just a quick example. As far as “If it works better than the wool shirt” I was assuming you wore the wool shirt in camp and to sleep, to add extra warmth to your down jacket or windshirt. A down vest certainly “works better” in as much as, it’s warmer than a shirt.
“Whether I want both the wind shirt and the rain jacket is a perennial dilemma, and the subject of many debates over the years on this forum. I do take both, and often wear the windshirt during rest breaks or if a chill wind picks up, when the big ballooney rain jacket feels like overkill” I almost always bring both as well (but it’s an XL, with hood at only 2.5 oz), and Ryan Jordan has made a compelling case for one too. I meant that if conditions were specific, you might not need to bring it. My thought was there was more overlap in use between a woven hiking shirt and a windshirt.
“ So the suggestion here is to replace the tank, the woven shirt, the windshirt, and the Puffy, with a Nano Air Light Hoody to go with the midweight wool shirt?” Yes. If it was consistently cold, the midweight shirt would be your minimum to hike in. Cool windy mornings you would hike in the shirt + Hoody. Still bring the down jacket for camp.
“That is lighter but would worry that the wool shirt would still be too warm to hike in. Maybe I don’t trust that it will stay that cool all the time.”
Well it depends on your definition of cold, and indeed how stable the weather remains. But in that case, simply replace the midweight shirt with a lightweight zip neck base layer. Those are comfy even in quite warm weather. Andrew Skurka put’s it this way: Select a base layer that will be comfortable during your highest exertion in the warmest weather you expect.
“In women’s they don’t seem to offer a hoody.” Sorry,not the ‘regular” Nano-Air, the Nano Air light:

The regular Nano Air would be far to warm to hike in, even in cold (not frigid) weather.
Maybe you cold give description of how you use the clothing you have listed, that would help clarify it for yourself as well as us? (And avoid assumptions like mine about the long johns)
“On switching to a quilt”
Only for warmer weather. In an open shelter like yours for a cold sleeper, a mummy bag is a warmer option.
“The Arc Blast is the only framed pack I’ve seen that is lighter than the 2014 Mariposa. And with the ridgerest I don’t have any other use for the GG sit pad other than its structural role in the pack. (Even the smaller framed GG packs—the current ones—don’t weight any less than the pack I have.) – I should probably have bought the DCF Haven 2 back when it was offered, but even though yes I could come up with the price it kind of made me hyperventilate. The Zpacks looks like the closest equivalent currently.”
Again, the only reason I suggested those is that you have specific needs to go super low with weight. It’s a lot of money for a small weight savings and no functional increase really. But that’s the point you are at: diminishing returns and high hanging fruit ;-)
