I know the new "foliage" color is quite odd (I really prefer the coyote brown instead), but since the black fleece watch caps are no longer authorized for Army use (phased out), there should be plenty on the surplus market. I've really grown to love the simple fleece watch caps (most of mine are made by Polartec). They are light, dry fast, can be rolled up just over the ears for better hearing, and can be pulled down onto the neck for better coverage. Since I have so many, I don't have a need to try something else, but for me, they work great. I use them for PT (the fugly foliage green color), I have a few black ones in my field pack and backpacking/hiking packs. They take up no room add no negligible weight and make a tremendous difference at night to keep you body heat in!
