Our Heirloom Cotton collection takes its name seriously. These sweaters — crafted from 100% soft cotton — are made to be kept. Worn, washed, handed down, and loved for decades. Heirloom Cotton is the fabric behind our beloved Flag Sweater, Sport Crew, Puff Sleeve Cardigan, Shawl Neck Cardigan, and our kids' sweater collection. It's breathable enough to wear year-round, substantial enough to feel like a real layer, and natural enough to keep you comfortable in every climate. Unlike synthetic blends, 100% cotton sweaters age beautifully — softening over time and holding their color season after season. If you're looking for a sweater that becomes a core part of your wardrobe rather than a trend-of-the-moment purchase, this is your fabric. Shop Heirloom Cotton sweaters in our full range of styles, colors, and seasonal prints. Custom sweater options available.
