I've been wearing black, wool, military-style watch caps for years at work. Having just lost my third one so far this winter, it was a perfect time to try something new. As one would expect, comparing the softness of cashmere/acrylic blend vs. old-school wool was night and day. I realized that I was taking my old hat off so much because my head started to itch -- not a problem with this cap. The pure wool cap was a bit warmer, but my head tended to overheat anyway, so it was good for me but something to keep in mind. I don't have a particularly large head, so I found the fit of this product better, since the overall length of the cap is much shorter than a traditional watch cap, meaning I didn't have to fold it over quite so much. My biggest complaint is the fairly large seam that runs the length of the cap, which I could feel against my head and would have to orient to the back.
Pros: very soft, good fit
Cons: not the warmest (though could be a pro), large seam
