Kinda late, but I'll third this. I just yoinked a continuous spray bottle of Coppertone Sport SPF 30 for my Biking duffel, and that's kind of important what with it being summer and all (but it'll help in winter too! don't forget about UV reflection off of the snow!).
I seriously agree with having it on and with you when biking, even trail riding where there's a lot of shade sometimes.
