Thin and stretchy.

The beanie is two layers of fabric- one black and one grey. For such a thin beanie, it is quite warm and wind resistant. The 5% spandex content gives it a snug fit without "relaxing" after wear (unlike 100% merino). I've worn mine for about 20 hours and it is still comfortably snug on my size 7-1/4 head. The knit is quite smooth and feels nice under a bike helmet for cool morning rides.
