Exactly the same for me winter cruisers over padded shorts.To add, it's good to have some reflectives on your legs, ankles, feet when cycling in the dark to stand you out as a cyclist to other other road users (distinctive leg movements). I often wear Altura winter cruisers over cycling shorts or padded tights when it's colder than 5 deg
Bib shorts with Ron Hill Tracksters over the top. Cheap as chips.
I have Ron Hills and a pair of warm cycling tights which don't have a pad. I wear bibshorts or padded undershorts under whichever I am wearing on chilly rides. The tights are a bit too warm above 12 degrees and the Ron Hills not quite warm enough below 8 degrees. Between 8 and 12 degrees, either choice suits me.Ron Hills are nice and long in the back too. Great on the bike - when I get off, I look like Max Wall!
