A sleeved blanket is a body-length blanket with sleeves usually made of fleece or nylon material. It is similar in design to a bathrobe but is meant to be worn backwards. The product has been marketed by various brands but the original company was Slanket created by Gary Clegg, then other companies like Snuggie, Snuggler, Doojo, and Toasty Wrap, copying the brand later. It comes with varying sizes, colors and qualities of materials but similar basic design.

A blanket is a swath of soft cloth large enough either to cover or to enfold most of the user's body and thick enough to keep the body warm by trapping radiant body heat that otherwise would be lost through convection.
