100% Linen. Piping in chalk blue. This scrunchie matches our Ana Leovy x Tombolo shirt in yellow. Linen requires less water to produce than cotton, and it's strong, breathable and absorbent. It's no wonder it's the oldest known fiber. We chose a nice thick weight because it doesn't wrinkle as much and travels well, while still being breezy. Machine wash cold, tumble dry low.
