Don't know if this helps Arrogcow,

Hasn't been an issue for me. The 11 oz PV keeps me warm in cold and windy weather and its cool in hot weather...no clue why, just is.

There's only 5 oz difference between a yard of PV and a yard of 16 oz wool as far as weight, but of course the materials are different.

My USA Kilt casuals are over 4 1/2 yards of material. There is a double layer of material up front with the aprons and a triple layer of material in back where the pleats are. Imagine that helps with the warmth.

Do my PV kilts keep me as warm as my wool kilts in winter? No.

Do my PV kilts keep me warm in winter? Yes.

And, just for clarification, I'm talking about temps down in the 20s and 30s F. Its cold here, but its not as cold as more northern Climes.
