These sun hats are made from natural straw or paper straw — listings include labels such as "100% Straw" and references to "paper straw" or "natural straw."
They’re generally marketed for women as "one size fits most," with listed head circumferences around 22–22.8 inches.
Brim widths commonly range from about 4.5 to 5.0 inches (examples include 4.5, 4.9, and 5.0 inches).
Many are described as roll-up, foldable, or packable — made with flexible straw construction that compresses for easy storage in purses or luggage.
Listings show pull-on styles and hook-and-loop (Velcro) closures; some hats also include an inner sweat-absorbing band for a secure, adjustable fit.
Many styles feature an open-top or ponytail opening so ponytails, buns, and updos can be worn through the hat while keeping the head cool.
Care instructions vary by listing but commonly recommend hand washing or spot/wipe cleaning, then line drying or laying flat to dry.
Crown heights in the listings are similar, typically ranging from about 2.0 to 2.3 inches.
