From desiginer’s website:
I am excited to offer you the pattern for the One for All Hat! I chose the name due to the fact that this hat fits me, my 14-year-old son and my 8 and 11-year-old daughters. You could make it in one color and leave off the pom-poms for a simple man’s hat or stripe or color block and add pom-poms for a more feminine version. This is a very quick and fun knit, perfect for a first-time cable project. There is an optional lining knit right into the hat.
