Spyro,

I went with 100% Merino Wool long underwear...nice stuff, I've been happy with it.

I plan on topping it with a Woolrich Alaskan Shirt. I'm looking at the Cabela's WindShear as my middle layer.

If the weather really turns nasty, I'll break out the foul weather gear, but I am hoping the use this combination most of the time.

Regards,
Steve
