Comfort, naturalness, hygiene, cosiness - the perfect combination of the two layers of this pillow: the bottom layer of washable sheep's wool and the top layer of cotton percale. Sheep's wool is hygienic and does not breed bacteria. Perkel cotton has a matt appearance, is thin, strong and durable. The pillow is soft and cushy thanks to the fluffy polyester balls that support the shape of the pillow. The pillow is breathable and does not interfere with the breathability of the facial skin. The fabrics used in the pillow absorb and evaporate sweat moisture. This pillow is from the Natural line, so it is made from high quality raw materials and no optical brighteners are used in the processing. The products are packed in cotton, durable, handmade eco-friendly suitcases with a transparent window. SUPERWASH sheep wool pillow is certified according to Oeko-Tex® Standard 100 quality requirements. If the impyle layer of this natural sheep wool gives off a specific smell, we suggest that you air it outdoors or wash it. Both the easily removable double-layered impyle and the pillow filling - polyester balls placed in a separate impyle - can be machine washed on gentle cycle or hand washed. The removable double-layered impyle and the pillow filling may be dried in a tumble dryer or in a warm, dry environment and outdoors on a hot day, but avoid direct sunlight. For more detailed information on the care of the SUPERWASH sheep wool pillow, please refer to the label of this product. Made in Lithuania
