We are lucky enough to ride year-round here in San Francisco. While most days require nothing more than a jersey and bike shorts, once winter actually hits, the riding gets cold. I know, I know–winter in California is not exactly winter in Minnesota but I have been colder riding my bike here than ice climbing in Canada. Morning temps hover in the low 30s, with the afternoon warming up to the 40s and maybe low 50s if there is lots of sunshine and little wind. This can make dressing for a ride difficult, so layers is key. Here is a look at some of my favorite gear that keeps me cranking out miles straight through the off-season.
