Microflannel sheets are an innovation that combines the comfort properties of premium European cotton flannel with the easy care properties of wool without the bulk or weight. Microflannel sheet sets combine the comfort properties of cotton flannel with the easy care and energy saving properties of wool. Microflannel is shrink-proof, pilling-resistant and wrinkle-resistant, making it suitable for deep pocket mattresses. Microflannel is energy-efficient and environmentally friendly, and washes and dries quickly. Its thermal design keeps you warm and comfortable. Made of 100% polyester, it is pre-washed and pre-shrunk, and uses softener for an extra soft touch. Available in a variety of colors.
