Lots of opinions, and much great advice given.
I have a Stoic Wraith windshirt. It weighs 2 ounces. Windshirts protect from the wind to shed off cold. If I'm in the wind, and NOT reaching for my windshirt, I think you all are spot-on, and I should be looking for a windshirt I like better! Mostly, the windshirt was put on over the Montbell jacket as an extra layer. I didn't care how it felt, because it wan't against my skin. However, if it could be doing double duty, and it isn't, well then I guess it's time to consider a replacement.
Which leads me to this....what's a good, breathable, comfortable windshirt you might suggest? For those that really find it invaluable.
I also like the idea of smartwool sleeves. I'll be checking those out as well, but will have to make the decision of which to go with.
