This unique material, in a blend of 85% linen and 15% wool, can be described as a warm and sustainable version of regular cotton flannel. The linen/wool flannel is soft, lightweight, breathable, and renewable. Since the wool and linen fibres breathe and transport moisture away from your body, garments made from linen/wool will keep you warm in the cold, even when wet, and cool in the heat. Wool has also natural anti-bacterial qualities which keeps it from smelling, and it cleans itself in fresh air. The flannel is perfect to layer with our viscose/wool.
