This "Polo Mesh Work Cap" was born from hearing many such voices. Made of thin polo shirt material, it has a soft and smooth feel. It's light and breathable, so you can wear it comfortably even in the summer without getting stuffy. [We want everyone to wear it. Size variations based on that thought.] For those with smaller head circumferences: M size for women and men with small head circumferences. For those who want a moderately relaxed fit, or for men and women with larger head circumferences: L size. Since it's quite roomy, XL size is recommended for those who prefer a big size. [Once you wear it, you'll be hooked...] The soft feel of the thin polo shirt material is comfortable to wear, and you're sure to get hooked once you put it on. It's light and breathable, so you can wear it comfortably even in the summer without getting stuffy. [Simple solid colors and accents] Available in two patterns of mixed colors. Mixed colors, which have a stronger presence than solid colors, are recommended as an accent for your outfit. A nakota tag is attached to the side for a little accent. We have thoroughly pursued the texture of the material, even down to the feel of the ribbing on the back, so you can wear it comfortably from "I'm off" to "I'm home."
