I'm still looking at getting myself an insulated synth jacket for things like AMR and winter touring and saving my PHD down jacket just for sleeping (it's too warm for riding in and AMR was down to either -6 or -11, depending on who you ask so it's unlikely I'll be experiencing much colder unless I start mountaneering or something)
This might be a house deposit worth of Albion but it's a pretty good example of layering for the cold.
