It was a bit nippy nothing more. I cycled in 3/4 longs, a light SS jersey, base layer & arm warmers only to find him self drenched in sweat this morning. Only thing to watch at 5:30 am is the hands, I've been needing my lighter winter gloves, which are actually a bit to hot, rather than XC gloves with glove liners, which are a little to cold.
