This portable sleeping cocoon is made specially from woven fabric that is impervious to bed bugs. The sleeping cocoon's tightly wound polyester threads are spaced only 1-micron apart (a span that's much smaller than bed bugs) to prevent 100% of bed bugs from penetrating the fabric. The durable polyester threads are impervious to bed bugs' teeth yet the fabric remains soft, pliable, and breathable for optimal sleeping comfort in a hotel bed. The sleeping cocoon creates an enclosed sleeping environment from the shoulders to the feet, the hooded top protects your head and neck yet allows you to breathe naturally, and the entire unit folds to fit in the included tote for ease of travel. 81" L x 36" W. (1 lb.)
