My answer, HELL YES. The high here today is 46 and im going riding. Cool thing, I was at the honda dealership yesterday talking to some people and i ended up buying this vest thing that heats up, it has different heat levels up to 155 degrees. Im pretty excited about trying it out today lol Other than that i wear the thermal underarmor under the leathers as well so i'll ride when it's in the fucking 20's.

Link for the vest if anyone is interested: Gerbing's Heated Clothing - Heated Lite Vest Liner

I'm gonna go ahead and agree that underarmor is the shit (esp the thick cold weather stuff), but without some type of heating element your still going to be cold in 45 and less degree weather. My perforated leathers probably dont help much there.
