I just picked this up last week and have used it at work. I work outside on the ramp at Pearson Airport, it is windy and gets nice and cold. This hat is really warm...the fleece lining makes it very comfortable and wind proof. The ear flaps are great and when tied down really keep my ears toasty.
I bought a large and it feels a tad small to me up top, but the ear flaps fit well.
Price is high, but it is made here and the wool is worth it. If you are looking for a great winter hat, you found it.
