Steadman, I'm repeating myself in case you don't scroll back to the first page. I have a top that is Capilene 4. Got it on sale last year during one of the semi-annual sales. I really like it. Very warm. Back in the day when Capilene came in only light, medium and heavy, I got a medium top and bottom and both are still wearing well. Unlike some of the newer stuff, they and my new top don't have a pattern woven into them, just plain smooth material, although the 4 top is kind of fuzzy on the inside. Can't beat this stuff as far as I'm concerned. However, at retail, it is pretty darn pricey.
