You’re right that down pants are not particularly useful if you get into the bag immediately. My backpacking partner likes hanging out outside the tent for quite some time to chat. Sometimes he does that when it’s dumping snow! I do like chatting with him rather than running into our tents at 4 pm and waiting for dark to arrive. Also, I ended up with the earlier stages of hypothermia when the wind blew on a ridge I was camping on from heat loss in my legs. It was scary. That prompted purchasing the down pants. I know, camping on the ridge was asking for that, but our entire goal was to get up on that ridge. The views were great.
My liner weight was an error. It’s 40 g each, not 140. I fixed that. I’m very happy with my gloving system. Unfortunately, I have Raynauds, so my hands can get painfully cold. I’ve tried going lighter, and I suffered. In fact, my finger once turned blue and went numb for 6 months because it got so cold (!!!). I rarely need the beefier gloves, and usually only wear them for a few minutes. But when I need them, I’m so glad I have them. Typing without sensation in one of your fingers is super weird and unpleasant.
Regarding the ice axe, I do sometimes bring crampons. My trips can get technical. I like the beefier axe because it works really well in mixed terrain.
Yeah, I bought an InReach since I posted this. It’s heavy. I bought it shortly before they announced the mini. Whoops. I’ll upgrade at some point. After I’ve heard so many stories, I’m increasingly convinced that it’s the 11th essential.
Maybe I’ll get a lighter shovel. I bought it for avalanche rescue after I saw someone’s aluminum shovel fracture. The heavier one is probably not necessary, although I just used it to shovel my driveway when the snowpocalypse came to the PNW. I think I was the only person within a 50 mile radius who owned any reasonable shovel.
Regarding rain pants, I want them to be full zip so I can take them on and off while wearing snowshoes. That adds a lot of weight.
I still need to figure out my pad and ground sheet system. I’m still not super happy with it. I’ve recently started carrying a heavy Tyvek groundsheet after reading Trauma and Pepper’s book on ultralight winter travel. It’s heavy, but I really like having a dry surface to keep my gear on. It keeps things so much drier! I definitely will take a look at that link.
I’m considering replacing the Catalyst with a Seek Outside Divide. It has more capacity and is waterproofish. It also carries loads better. The Catalyst is acceptable for this, but not great.
Unfortunately, as I get more experience with winter camping, my base weight gets heavier and heavier! Funnily, my 3 season kit gets lighter and lighter with experience.
