The Bison Brain Warmer, our most popular hat,  will keep your mind off the cold!  This hat is knit with our Bison Ranch Yarn; a 25/25/50 bison-alpaca-wool blend, and lined (10" with a 2" unlined section at the top for balanced heat exchange) with our luxuriously soft  Bison Cloud Yarn; a 50/50 bison-alpaca yarn, and topped with a hand-cut and  elk or deer antler button.  The long style allows you to cuff the hat brim or roll it down to protect ears and neck during a harsh wind.  You don't get any more Rocky Mountain than this!  Field tested by fishers and hunters and they all said, "This hat is warm!" Additionally, this hat was chosen to travel with a group expedition to Antarctica in March of 2016. Regular: 20"-24" Crown of hat to hem: 10"         Pun'kin: 24" - 26"    Crown of hat to hem 11" All natural. No dyes or harsh chemicals used at any time during the processing of the fibers.  Domestic USPS priority shipping included in price. Handling fee applied at checkout.

    Last year I ordered the Multi-Mitt and use them for walking, hiking and fishing. This year I ordered the Bison Brain Warmer hat, it a great looking hat with the classy logo and elk button, it has the ‘Love of the Outdoors’ look. Thanks.

    I bought a beautiful piece of craft and got the warmest hat I ever had. It is so soft and cozy. I can’t wait to take it out on another day by the river fishing, or to try it out at a Christmas market here in Sweden. Thank you!

    Bought as a present and he loves it – says it’s the warmest hat he’s ever had (really helps if you don’t have a lot of hair :)). Great workmanship and good people to work with.

    Sometimes you buy something for the heck of it not thinking about needing it. I bought one of these before going to New Brunswick, Canada for a three week business trip in January- February that called for spending about 10 hours a day in the field. It never got above 25f and was mostly below zero. I lived in this hat and was grateful for it every day.

    My new favorite hat. Top quality workmanship and material while being unique and stylish. All that and amazingly warm too. You can’t top this hat.

    This hat is so much better than the “big name” merino wool or windstopper fleece hats I have previously used. The finely handcrafted Brain Warmer Hat has the perfect balance of warmth, breathability, soft comfort, and fit. It is now my favorite hat especially for cold, active winter sports.You nailed it Jennifer!

    A good product. Well made, warm and soft – and it doesn’t squish your head.
    If it was a bit longer it would cover your entire ear which helps in the wind. [Note: We have added extra length to help with this issue. Thank you for your comment. – Jennifer Olsson owner/manager]
