Susan -- I put a Craft base layer under my Terry thermal hoody and I haven't noticed that the hoody holds moisture. Maybe because I wear the hoody only when it's really cold (below 30 degrees) and in temps like that, I don't stop for nothing! I'll have to keep in mind not to wear it as a base laye--thanks much for the tip! The smartwool hoody sure looks nice, tho. Should have put it on my Santa list! No doubt the x-small will sell out by the time I make a wish list for my birthday.
