Editing Blanket sleeper (section)

=== Materials ===
The range of materials used for [[mass production|mass-produced]] blanket sleepers for children is severely limited, as a result of stringent U.S. government-imposed [[flammability]] requirements.  Essentially the only materials used since the 1950s are [[polyester]], [[acrylic fiber|acrylic]], and [[modacrylic]], with polyester dominating. Unfortunately, this can have a negative impact on comfort for many wearers, particularly children with [[eczema]]. A small number of sleepers are made from cotton.

Adult-size sleepers, especially those sold by small Internet businesses, can be found in a wider range of materials, including natural fabrics such as [[cotton]] [[flannel]].  Some web businesses also offer sleepers in natural fabrics for children, but only outside the U.S.  In particular, special ''eczema sleepsuits'' for children, made of cotton and with built-in mitts designed to prevent scratching, are available from specialty stores in the [[United Kingdom|UK]].

The fabrics used in most blanket sleepers have a strong tendency to [[Pill (textile)|pill]].  Although this does not adversely affect the garment's functional utility, it has the effect that a used garment can be clearly, visually distinguished from a new one after only a small number of wearings or washings.

Decorative features such as appliques or printed designs usually follow juvenile themes, and are designed to make the garments more attractive to the children who wear them. Some adult sleepers can also have appliques on them, but those tend to be from Internet clothing suppliers who offer custom-made sleepers and tend to be of favorite cartoon characters or items that the wearer had in childhood such as teddy bears and animal representatives that they had as pets.
