Cut and sewn in the USA by the legendary Gitman Bros., our flannel is crafted from premium 100% cotton twill, double-brushed inside and out for an exceptionally soft, cashmere-like feel. The double-brushing process raises the natural cotton fibers, creating a soft, warm hand without unnecessary bulk. At 4.8 oz., the fabric offers an ideal balance of warmth, breathability, and everyday comfort, whether worn on its own or layered under a sweater or jacket. It's a timeless addition to the fall and winter wardrobe.
