Chef,

You still have the J & G yellowjacket windbreaker, right? (If I remember correctly from a previous thread on big men's windbreakers in the C&A forum).

I use the same jacket as my outer, windbreaker layer.

I use these two under it for really cold days:

base layer - Minus 33 midweight merino wool longsleeve 1/4 zip

midlayer - a cheap polyester running/athletic shirt (any will do) - that is one size larger than normal, so it's a little loose if worn alone, but fits perfectly over the wool shirt.

Yellowjacket on top.

If you do sweat, the merino wool is both good at wicking, and also keeps pretty good insulation value when/if wet.

The Minus 33 shirt is on clearance sale in that gray color, and they have XXXL available. (I use XXL, and my yellowjacket is an XXL). I highly recommend you try the wool shirt as a base layer.

So far, this combination has proved perfect for me in 7 degree F weather with no wind, and actually a little too warm for upper-20's with moderate wind. Give it, or something like it, a try and see if it works for you too.
