Most costume masks are labeled for ages 10 and up or 14 and up; the sport-style helmet is described as suitable for youth players.
Costume masks are typically molded from sturdy plastic and fasten with a comfortable elastic strap for wearing during play or dress-up.
Listed dimensions across products vary: overall heights range about 9.5–13 inches, widths about 5–10 inches, and maximum head sizes are listed from about 8.25 up to 24 inches. These ranges reflect different listings rather than a single product.
Costume masks typically use elastic straps for a flexible fit. Sport-style helmets may include a slide-adjustment system and an adjustable strap for a more precise fit and stability.
Most listings are for costume use—Halloween, horror, or TV/movie-themed dress-up—while at least one listing is intended for street/roller hockey.
