I'm trying to work out what sort of clothes I need for this Canadian trip, and I'm confused about what to wear when it's -10 degrees C outside and 20 degrees C inside. See, I'd generally assume that when it's -10 degrees, you want to wear thermal baselayers - but I wouldn't want to wear thermal underwear indoors. So I'm trying to figure out what order you put the layers on in.
Also, sitting in a wheelchair, I get colder than people who are walking around. But I'm loathe to get one of those wheelchair-user leg-cosy things in case I need to stand up for some reason.
