long sleeve jersey in the cooler months but once it gets hot I wear long-sleeve sun shirts. I put a wicking camisole type top on over my sports bra and then my long sleeve sun shirt. I have 3 different ones - all bright colors, love the venting and the air flow. As I don't race I have found them to be extremely comfortable for both day rides and touring. I have a front rack bag so I don't need the pockets a jersey provides.
