I am not a fan of the cold. AT ALL. But there is help for me!!!! I wore this 'Stay Warm' Base layer shirt by Nike and I didn't want to take it off...I wish it was my skin! I can't remember ever not being cold when I'm out in the cold, I am just miserable and no fun at all to be around. This shirt has changed everything!! I'm not saying I will be singing the same tune when it is -5, but for a person that really dislikes the 30s, this is a saving layer! I HIGHLY recommend it. Under Armor makes a version of the same thing, but I decided on Nike because of the thumb holes. Same price, same look, same overall effect, but when you have loooong arms and a looong torso, you really appreciate when things fit!!
