Looks like you've got a pretty good gear list, there!

Some specific observations that came to my mind that you can take or leave, (YMMV ):

Gear:
You might be able to dispense with the silk bag liner by bringing a better sleeping pad. I tend to get very cold at night and find that a sleeping pad with a high R value is essential, since one loses a lot of heat to the ground. Depending on what year your Deva pack is, you may have the side holster designed for a 1 Qt nalgene bottle that can hold a 3/4 thermarest quite nicely.

I always carry a space blanket sleeping bag in my emergency kit as one of my "10 essentials". Besides emergency use, this also can just make a cold miserable night immediately warm and toasty. One of the nights I was up in Denali I shivered miserably for about 5 hours and eventually gave up and popped it over my sleeping bag around 2am and within minutes I was warm for the rest of the night.

For your tent footprint, have you tried Tyvek? It works well, is cheap, and is ultralight. You can get sheets of it at Home Depot.

Can you consolidate your water bladders/bags at all? I generally just use one 3L bladder, and also have an MSR water bag that I use for filtering water.

Clothes:
I tend to just bring two sets of clothes - one for hiking in every day, one for camp/lounge/sleeping. Merino wool can be reworn for days on end without stinking, so that's something to consider. I generally only bring three pairs of smartwool socks. One to wear most days, one spare dry set, and one night set. I know it's a little gross, but I find that I get less blisters when I am wearing, erm, "seasoned" socks that have a nice coating of skin oils on the inside.

I almost always take some sort of dip or cursory rinse-off before changing into my night clothes. Even just a rinse with a liter of water makes a world of difference to rinse salt off and hit the critical spots. Also, if water is more abundant I'll do a little laundry mid-trip for quick-drying synthetic tops and hiking pants, and undies.

Another tip about the underwear - dunno if you've ever used a menstrual cup? I wear mine non-stop when I'm backpacking even if I'm not menstruating. It just keeps things tidier in the underwear dept and I can bring less pairs. (Note: Do not try this with tampons. Wearing tampons without having an active flow can lead to TSS, and besides it's just... really uncomfortable.) In contrast with the socks, I don't recommend "seasoned" underwear!

If you have to bring high gaitors anyways, and you don't anticipate more than occasional bursts of rain or merely light drizzle, you can often get away with just a poncho + gaitors, which is lighter than a full jacket + pants + gaitors.


It sounds like you're going to have an awesome trip!
