Waterfall Mammoth Flannel from Robert Kaufman #31154

Waterfall brings a deeper, moodier blue that feels classic and versatile, the kind of color that anchors a wardrobe. The fabric itself is the signature Mammoth Flannel base: dense, soft, and incredibly comfortable with a reassuring weight that feels premium as soon as you touch it. It’s especially good for garments that benefit from structure without stiffness. Think traditional flannel shirts, cozy tunics, casual dresses, drawstring pants, and unisex loungewear, as well as outerwear-leaning pieces like shirt jackets or cozy overshirts.
