When the wind swings round to a Northerly or Easterly (as it just has) and there is an extra nip in the air, I wheel out a 1990's vintage Swedish army M90 cold weather coat. For such a lightly padded coat, it is amazingly warm and it keeps your body heat whwere you want it ! It is long and tough and paired with a lightweight fleece underneath, some gloves and a warm hat - good to go
