I have way too many gloves.
I have Pearl Izumi Elite Gel Vent for the really hot days
I have Pearl Izumi Select Gel FF for anything above 60F to 80F
I have Pearl Izumi Select Softshell for 45F to 60F
I add a Pearl Izumi Thermal Lite under the Select Softshell sometimes if it gets below 45F
I use a Pearl Izumi Pro Softshell WXB 3x1 with the included liner for anything less than 40F
For running it's a lot easier. A thin cotton or wool glove if weather gets below 50F and if it dips below 35 I start wearing the PI Select Softshell.
I probably have more money in gloves than others have in their bike...
