sack

A portable, personal sleeping environment designed for use within temporary accommodations. It serves as a barrier between the user and potentially unclean bedding surfaces often encountered in hotels or other lodging establishments. These personal sleep spaces are typically lightweight, compact, and easily transportable.

The utility of such items stems from concerns about hygiene and comfort when utilizing shared bedding. They provide a sense of security and cleanliness, particularly for individuals with sensitivities or allergies. Historically, the practice of using personal bedding while traveling dates back centuries, with modern iterations evolving to prioritize portability and ease of use.
