Common materials include polyester (100% or blended), cotton/polyester blends (for example 60% cotton/40% polyester), and polyester/spandex blends (for example 96% polyester/4% spandex).
Closures commonly used are full-length zippers, snap-front closures, and front buttons.
Common decorative details include applique patches, embroidery, screen prints, patches, and occasional bows.
Many styles include functional front or slash pockets (typically two), and some note partial or full lining and practical features like safety zipper guards.
Common details include ribbed cuffs and rib-knit or striped rib trims on the collar, cuffs, and hem; some puffer styles note bubble-style cuffs and waists.
Snap-front closures and full-length zippers (often with safety zipper guards) are highlighted as kid-friendly options that simplify layering and dressing.
