Been out for a few rides... but brrrrr.... layers to start and shedding as the ride progresses... but still experimenting with head cover... never seems to be right, too hot and sweaty or too cold... yes 48F in SF.
I have a shell cover for for the helmet, and some crazy head cover with ears... but probably need a thinner layer
I have this one, good for the first 4k (cannot upload) so here are the keywords: Hikenture skull cap helmet liner with glasses holes.
