Biking advice in San Francisco

[Trek420]

Should I bring arm warmers? A jacket, too, for riding?

Dress in layers. If you don't like the weather here wait 5 minutes. We go from fog to sun to fog rain sun wind sun fog .... and back again. Then our wonderful micro climates. and go from sunny meadows to shady redwood grove to along an orchard back to mean city street and back to redwoods on a short ride. And wherever you are it's the opposite weather when you go to Marin.

It's one of many reasons I love it here.

My outfit is jersey, vest, arm skins....shorts of course Skins go up and down, vest up down or off ... that way I go from rain jacket to short sleeves as needed. Many here like the jackets where the sleeves are removable....
