Cold! This was the coldest day I've commuted yet, about 35 in the morning (there was frost on the ground). So I had to wear my alertshirt windbreaker for the first time. It's lined and it worked very nicely, though admittedly it's a bit sweaty when I get into work (Maybe I need to get a long sleeve wickable under neath, the short sleeve worked nice, but the warms were sweaty).

Still, it's a refreshing way to start the day
