For hand washing (highly recommended): Rinse in cool water after use. Hand wash with gentle, eco-friendly soap in cool water. Air dry in the shade; do not expose to direct heat. Keep flat or hang to preserve the fabric. Avoid storing in high-heat areas like a car trunk. For machine washing: Use the cold water cycle only. Hang to dry; avoid using fabric softener. Do not use heat drying to protect the UPF coating.
