5 stars for comfort and wicking. I have these In gray and there's a noticeable difference in the fit between black and gray. I need to go a size up in black. I wonder if it's the dying of the wool. This is also true of the Flanders base layer. I have Black and gray in size medium and black is very small. Don't let this deter you. I have a lot of love for these garments. Just go up a size if black is your color.
Likes: Castelli quality. Dislikes: a little thin and slippery which means your feet move more inside your shoe unless you really crank down on your Boa (or whatever cinch you have on your shoes). But then high and tight Boas take away from longevity and comfort. If I was racing, maybe these would be good but those days are over for me. Prefer a little more thickness in my socks, even on a hot day.
