Flannel
— natural fabric of cotton or wool type. It is pleasant to the touch and quite versatile: it is well suited for both warm and even hot weather (due to naturalness), and for cold weather (it saves heat well). The disadvantages of flannel are the tendency to wear (the appearance of "pellets") with prolonged use, as well as high hygroscopicity — the fabric absorbs moisture well and dries for a long time.
