The Waxed Cotton Curveball Cap


A tribute to George “Stormy” Kromer’s semi-pro baseball legacy, this waxed cap will immediately transport you to a simpler time.



  • 10 oz. paraffin-treated 100% cotton duck
  • Polycotton lining
  • Six-panel crown construction
  • Lengthened brim
  • Made in the USA with globally sourced materials
  • Spot clean only




To get your size, measure comfortably around your head where your cap will sit, with a tape measure. Take that number in inches, divide by 3.14 (pi) and round up to the nearest eighth. This is your cap size. See the chart for size conversions. You can also print out our hat sizer, click here.

    Runs one size big. All my Stormys are 7 5/8, had to go with a 7 1/2 with this model.

    I bought two of these last year. One in each color. I have a huge head (7 7/8") and this cap fit me just right. I'm ordering two more as the ones I ordered last year are looking dirty as I wear them every day! Thanks for making a great product.

    5th Stormy Kromer hat and I love it. Was unsure about sizing - went down a size from what I normally wear and it seems to be just fine. Great for casual everyday wear and a different twist to SK. May just have to get a 6th!

    Sizes doe not fit. Bought this hat the first time and it was way larger than standard sizing. Returned it for a smaller size and it was still way too big. Stormy Kromer please get your sizing in check. Returning my hat for another one -- if this size doesn't fit Im done with the Kromer Caps. ~~We apologize for all the sizing issues you are having - and thank you for letting us know; we will forward this information on to our Quality Control department. If you still have issues with your new hat, please give our customer service department a call. We would like to make this right; call toll free 888.455.2253 - SK ~~
