The inside of the FUN weighted sleeping bag is made of patterned cotton (Oeko-Tex certificate). The outside is covered with minky fleece for a comfortable feel. In the middle of the weighted sleeping bag is a layer of silicone filling material. This guarantees pleasant warmth while sleeping. On one side of the weighted sleeping bag there is a matching zip that makes it easier to use the sleeping bag. The end of the zip is of course well secured against coming loose during sleep.
Washing instructions: The sleeping bag is suitable for washing with water (30 degrees/hand wash), lay flat to dry.
