The Millie Kromer Cap

(13 reviews) Write a Review

It took serious engineering to get the perfect hat compatible with hair styles that need space to cascade. The Millie Kromer— named for Stormy’'s niece Millie, who traveled by train to deliver materials between Kaukana and Milwaukee, —gives your pony tail room to swish and sway while still providing pulldown earbands. Genius.



  • 23-25 oz. 80/20 wool/nylon blend
  • 100% cotton flannel lining
  • Six-panel crown construction
  • Pull-down earband
  • Hole for ponytail
  • Made in the USA with globally sourced materials
  • Dry clean only

How to use the earband

Listen up! You know how you cup your ears in a maelstrom of noise trying to hear someone ahead? How you make little finger pockets around your lobes to catch all the sound waves and block what’s behind? Go ahead. Try it now. In that position, you're basically poised to pull down a Stormy Kromer earband with ease.

I was disappointed the material used to make the Millie I received for Christmas was thinner than my husband’s Stormy Kromer. As a rural carrier I realized it was thinner while working during the recent cold snap. My right ear was getting cold while delivering mail even though the ear flap was in place. This didn’t happen when I had borrowed my husband’s hat. I would have kept using his hat except I wished it had the opening for a pony tail.

Hi Kelly - we use the same weight wool for the Original Caps and Millie Caps (23-25 oz.). Was your husband's cap insulated? Please feel free to call us at 888-455-2253 to discuss further.

I got this because I my job requires me to go outside all day long. I already own a Petal Pusher, but I like to wear my hair up at work. The Mille fits the need perfectly! I can pull my thick hair through the opening easily and the "Kroner flaps" can still do their job. Since receiving it I have gotten many compliments on it. The material seems a little thinner but my head stays just as warm as in my other hat.

I LOVE this hat! The fit is awesome and allows for my ponytail. And it does not get blown off my head in the wind!.
And shipping was super fast! I placed an order on black Friday and it was delivered Monday morning! You just can't beat that!!

I purchased this as a gift for my daughter, who has long thick hair. She loves it, but says it is a bit hard to get all her hair through the hole. This is her second Stormy Kromer.

Best cap ever! I followed the directions for the measurements and it fits perfectly. It is very well made. I’m so impressed that I will be ordering other items soon.

Absolutely lovely hat, BUT the measureing instructions gave ma a size 1/4 size too small. Returned to exchange. Hoping it works out.

Got this for my girlfriend for her birthday a few weeks back. She has a few Kromer's that she loves wearing, but would always get frustrated when trying to put a pony tail in while wearing her Kromer's, this was the perfect fix! She loves it.

I have at least a half dozen SK hats; this one is absolutely my FAVORITE. Even in gale-force winds, this one STAYS ON. I wear my hair in a ponytail more than I realized; the other styles fit better with my hair down. This one is not only comfy and warm whether I have a pony or not, but there has never been a time when I have worn it when I did not receive at least one compliment on it. LOVE. THIS. HAT.
