there's certainly a tradeoff to be made here. putting on three extra layers just to go to the store is a pain. I do find that layers are much more versatile if you're going to be spending a lot of time outside or going in and out of spaces at a wide range of temperatures. with only a winter jacket and a t-shirt, I am likely choosing between being way too hot or way too cold. my winter coat is pretty bulky, so if I'm not wearing it, I'm carrying it.

when I'm going out for a while in the winter, I like to wear a cotton shirt, a wool sweater, insulated vest, a medium-weight windproof jacket, and a mostly empty backpack. if I get too warm, the vest and possibly the sweater can just go in the backpack. with this setup, I can be comfortable at any temperature from 30F to 60F without having to hold onto anything I'm not wearing. on really cold days, I swap in my heavy winter coat.
