+1 on wool
I bought an Under Armour Coldgear top and couldn't stand the funky smell that does not wash out, even after repeated washings with vinegar in the wash. Got a Smartwool top (and bottoms too) and wool socks and I wear the whole bit all week long with no smell at all. I've noticed the wool also breathes much better.
It's a little bit more expensive but definitely worth it.
