floppy sun hat

Materials shown include 100% polyester, 100% recycled polyester, cotton/denim, and nylon.

Brim lengths range from about 2.25 inches up to 6.62 inches, with common sizes listed around 2.75 inches and 4 inches.

Most listings specify UPF 50+, which corresponds to blocking roughly 97.5%–99%+ of harmful UV rays.

Care varies by style: many are machine washable and recommend line drying or laying flat to dry; some advise hand wash and line dry; a few specify spot cleaning or wipe-clean only.

Some hats use quick-drying fabrics and wicking liners, plus water-friendly foam brims that help the hat keep its shape when wet.
