Looking for a new hat...

[M&P45]

Not really a beenie, but I wear mine down to around -15. Plus it's guaranteed to piss people off if they can read Arabic.

I have that hat and love it! I wish they made that in a beanie.

These may be expensive for a hat, but they are worth it in my opinion. The merino is soft on the skin, breathes well, doesn't get clammy if it's wet, and won't make your head itch despite a tight fit. The knit is not windproof, but it is warm. I have bought several of their products and will buy more if the need arises and the funds are there.
