Does anyone have a good suggestion for something to keep my upper body warm in the morings on the way to work. Right now I leave the house ate about 5:30 AM. It's not too cold here now but I know it's going to get colder in to Fall and my goal is to commute year around. I just started commuting in May so I missed last Winter.
The facts!
-North California is where I live sometimes low 30's in Winter and 100's in Summer.
-I need to be able to fit it in to my small Camelback on the way home when it is much warmer outside.
-Short commute about 4.5 miles each way.
I was thinking of something like "under amour". Is that stuff any good? I was also considering a vest?
When I first started commuting in Spring I would wear a jacket in the morning and have to tie it to my rack on the way home. I no longer have a rack.
I also plan on commuting in the rain!
