Quayglass Hat

I was looking for a summer hat that wasn't just your average hat. This hat was born from that idea.

Made from 100% natural kuai grass, native to Southeast Asia.
This material is perfect for summer as it has a firm texture, is lightweight, and is breathable.

The center-fold crown and approximately 6cm brim create a natural shadow while giving a clean look to the face.
The contrast of the natural body and black ribbon will enhance your summer style.

It is harder than a typical straw hat and is less likely to lose its shape.
The size can be adjusted using the adjuster on the inside.

Recommended for:

• Those who are concerned about their straw hats losing their shape

• Those looking for a light yet sturdy material

• Looking for a summer hat that suits you?

• Made with 100% natural kuai grass

• Lightweight, breathable and firm material

• Robust structure that won't lose its shape

• Natural and black sophisticated coloring
