The thing that bugs me is around here it'll start at the low 30s and reach the 60s or 70s in the afternoon. You either start out underdress or end up overdressed. I get annoyed removing and attaching liners all the time so i usually deal with a cold morning commute so i can have a carefree afternoon commute.
40° is about the magic number for me, at least on longer rides. All my regular gear— pants, jacket, boots, gloves — all work great down to 40°. Below 40° I need to plug in my heated gear to be comfortable if I'm going to ride for longer than 10-15 minutes. I can sometimes suffer through, but why do it?
