I wear a tee shirt and shorts
and also keep with me a thin cotton cardigan tied around my shoulders
if it gets too cold I can wear it over my arms and buttoned behind the small of my back
for longer journeys where I may spend a while sitting still at my destination I keep a pair of track pants rolled up in the bottom of my backpack
if its really warm I keep my bag in a narrow basket on a rack behind the seat
I used to wear wool gloves under a pair of cycling gloves along with a balaclava, but it does not get cold enough in winter anymore
