Our Marshmallow Gauze feels like you’re getting enveloped in fluffy marshmallows. Triple-layered gauze adds breathability and smooth airflow while maintaining its natural softness and lightness. This unique triple-layer gauze is specially developed by UCHINO. Using long-fiber special cotton, the outer and inner layers that touch the skin are made from the softest fabric, while the middle layer is made from durable cotton. This combination of durability and softness creates a gauze like no other. This three-layer gauze is patented by Uchino, and only UCHINO can produce this material. In Japan, it is so highly regarded for its comfort that it has earned the nickname "Good Sleep Pajamas" due to its reputation for promoting restful sleep. Its softness is so outstanding that it is recommended by the Japan Atopic Dermatitis Patients Association. UCHINO pajamas provide balanced breathability and excellent heat retention, making them warm in winter and cool in summer, perfect for all seasons.
