Our flannel is double brushed, so the fine hairs of the cotton are whisked up into a soft fuzzy layer surrounding the fabric. This makes flannel the warmest, softest and coziest fabric. It’s great for cold nights or when you want to sleep with just a sheet that has enough weight and warmth to keep you snuggled in. Flannel is a medium-weight, plain-weave fabric typically made from cotton. It is brushed on both sides to raise the fibers, creating a supple, fuzzy surface and an extremely soft feel. If you look closely, the fuzzy hairs of the cotton resemble mist rising off a pond in the early morning. Cotton is 100% organic, sourced and woven in Portugal.
