And on reflection shouldn't have

. By "dark" I meant "not bright sunlight". - dawn and dusk. I agree, flourescent only works properly when there's some light.
But speaking of clothing, since I've never really ridden past mid-october... and I don't want to stop unless it's actually snowing/sheet icy/not safe to.... what should I be thinking about?
I'm a (un)naturally hot person. As soon as I start moving I warm up a lot - I don't think it's just because I'm so much of a biffa, but that's probably partly the cause. When I weighed about 70-75kg (not the 90-odd I currently do) I was still always hot compared to everyone else.
When does one add arm warmers to a short sleeved top, and when does one progress to long sleeved tops.
When does a windstopper gilet type thing over the top of something quite thin become insufficient and one should move onto a softshell.
What about rain? I'm yet to find (or look for) a really pack-down-small-able rain cover type thing... that I won't instantly roast in as soon as I put it on.
Maybe something water resistant but still very breathable (is that a thing?) would be best?
