Most styles are made from polyester (including soft plush polyester) or acrylic. These materials are used across adult, kids, and baby/newborn styles.
Care varies by item: baby plush pieces typically recommend hand wash and lay flat or hang to dry; some knit caps recommend machine wash cold and line dry; and some listings specify hand wash in their care fields. Check the specific product listing for the exact instructions.
Some Santa-style hats include reversible sequins (flip red to silver), faux fur cuffs, and pom-poms for extra decoration.
The listings cover adults, kids, and babies/newborns: some hats are sized for adults, others for kids, and at least one set is described as suitable for newborns.
Sizes include adult general sizing, kids sizing, and baby/newborn sets. Several knit caps are listed as "one size fits most" up to 20 inches. Example listed dimensions: a sequined Santa hat is 15" high × 9.5" wide; a baby hat/stocking set is about 13" tall × 8" diameter; some knit caps are around 9.5" long.
The listing recommends indoor use only for the sequined reversible Santa hat.
The hat and stocking are made from soft plush polyester described as having a "super soft feel," and the description notes the material is "perfect for sensitive newborn skin." Care is hand wash only, with hang or lay-flat drying.
