Was looking for a nice thick wool beanie as I live in MN and it gets below 0 quite often in the winter. I snagged this one and was quite surprised at how thin it is but decided to try it out anyways and so far it's working, although it hasn't been under 20 degrees yet. It is nice that it's rather large (and I have a large head) so there's plenty of material to roll up the bottom and still cover my ears. It's also not super tight on my head which is another plus as I get headaches real easy from things squeezing my head. All in all it's a super nice beanie and I like it a lot, I'll just have to see how well it keeps me warm when it actually gets cold up here.
