aaawww - looky them, aren't they cute, calling it "winter"....

20 C during the day and 5 C at night is the same as the lovely balmy days of early summer we're having here...

(But to be slightly on-topic - the most important thing to me when it gets chilly is not many layers, but a single windstopping layer all over. I'll use long tights, full-finger gloves and a thin skull cap long before I start adding extra layers under my jacket.)
