Material: 97% Bamboo Rayon | 3% Spandex Care: This is the best way to wash your bamboo clothing: Cold water; Delicate cycle; Turn off agitator if that is an option; With like fabrics (bamboo only); Layette should be washed inside out, zipped/buttoned up to decrease piling; Sleep bags should NOT be washed inside out, but should be zipped up completely to protect the inner quilting; Kyte BABY does not recommend using the dryer. We recommend hanging or laying flat to dry. Open your sleep bags when drying them and point a fan towards them to help drying time indoors.
