Thanks all! I have a good collection of wool socks.
I will actually be packing two or three weeks early for the trip due to our summer vacation. And of course aside from underwear it is an entirely different collection of clothing due to it being mid summer here. Another option is borrowing my husbands Uniqlo puffer which fits me well. It’s not a packable one but it is nice.
I hesitate to buy a longer puffer online. The hip fit is hard on me and often to fit my hips I size up and then it can be too large on top. I will either buy out of season here, borrow from family, or go shopping in person in Portland on day one of the trip.
