The Olie Shearling Sheepskin Hat in Black

I loved this hat, but the first one I ordered in size S was much too tight. Then I ordered a size M, and it fit my head, but doesn't cover my ears! I have a small head, so I'm very surprised that I'm having such a problem finding the right hat. I'm going to order yet another style, to see if it does the job! Wish me luck.
