Shorts even when it's very cold (my legs never get cold) and normally sleeveless if sunny or short sleeves if overcast. Between 65 - 70 degrees is perfect riding weather for me. Anything over that its hot and I get whiny!!!

Saturday here is was in the high 80's. I tried to mountain bike but the heat made me queasy. Sunday it got cooler around 68. Did 54 miles, piece of cake. The temp is a make or break for me.
