I used the black one twice after purchase and washed it. The light blue one is unused, but it doesn't have the package. I will waterproof the item before shipping (^^) Material: Polyester/Rayon Size: Free Features: UV protection, cool touch, quick-drying and absorbent Made in China Caution: *Color may fade or transfer, so do not soak or wash with items of different colors. *Hang to dry with the elastic part facing up.
