I used to feel the same way - wool, are you nutz!?!

But some wool is as soft and smooth as silk. I kid you not. I have a wool jersey by Wollywarm from Rivendell that I wear nearly nonstop in the winter months.

People are probably sick of me harping about Smartwool, but go over to the TE shopping section [shameless plug] and look at the Smartwool microweight tee shirts and longsleeve crewnecks. Soft and lightweight and wonderful. I've worn the microweight longsleeve crew as a base layer on cold morning rides and it works great.
