adidas Jm3063 Two Tone Beanie Unisex Hat

Hello, OSFM (One Size Fits Most) means "one size" and is the standard adult size. Thanks to its flexible structure, it adapts to most head shapes, it is not larger than the standard size.

Hello, this beanie is unisex and one size (standard size). If you see a size S option on the product page, it may be a different model or color variation. I cannot share exact measurement and size difference information for the JM3063 Two Tone Beanie, but thanks to its stretchy structure, it comfortably adapts to different head circumferences. For exact sizing comparison, we recommend checking out the size chart on the product page. If you know the circumference of your head, you can make a clearer decision from there.
