There are no better cool cotton weighted blankets than ours! Cotton fabric shows good durability and has a high water-absorbing capacity. It has good breathable characteristics and low thermal conductivity; therefore, it is ideal for all seasons. It prevents overheating in the summer but also preserves the warmth of the body in the winter. It is recommended for people with hypersensitivity, those who like to sleep in a cooler environment or like natural fabrics. We use a very thick type of cotton that can hold the shape of the heaviest blankets. All fabrics are certified by Oeko-Tex 100 Standard making them safe for anyone from birth onwards.
