When you just cant get warm then try the Minus 33 Midweight Crew Neck Top. It is a great base layer under all sorts of clothing and for all activities. Your son will appreciate it under his football jersey for that cold snowy game.
Comfortable. Remains to be seen how durable it will be.

Soft, warm, nice fit, not scratchy - perfect. My father complained for 30 years that he couldn't find nice woolen undershirts like he used to get in Europe. I got him one of these and he was finally happy!
