Under Armour cold gear long sleeve mock + jacket. I have one of those fleece lined bandana dealies, too. Nice.
If it's cold, I throw a mid-layer in to the mix.
If it's warm, I ditch the jacquito in favor of hoodie. At this point, lose the bandana, too.
If it's real warm, I ditch the hoodie in favor of UA + t-shirt.
If it's 40+ degrees, I'll just wear a t-shirt.
