Regatta Mammoth Flannel from Robert Kaufman #31156

Regatta has a clean, nautical energy that feels crisp and classic, especially appealing if you like blues that lean slightly refined. The Mammoth Flannel base brings warmth and softness without sacrificing structure, making it an excellent choice for apparel that needs to look good and feel even better. This one works beautifully for button-up shirts, cozy shirt dresses, lounge sets, and lightweight outer layers. It’s also a strong pick for matching sets or unisex garments thanks to its timeless color and dependable hand.
