100% organic cotton. GOTS, Organic, certified by CU1094701.Check the care label: Always prioritize the specific instructions on the garment's care label, as some items may have different care requirements. Wash in cold water: Organic cotton is best washed in cold water (max. 30°C) on a gentle cycle to prevent shrinking and color fading. Turn the garment inside out to protect the fabric. Choose a gentle detergent: Use a mild, eco-friendly detergent that is free of fragrances, bleach, and fabric softeners, as these can irritate delicate skin and damage the fibers. Air dry or tumble dry low: Air drying is preferable for organic cotton as it helps maintain the shape and softness of the fabric. If using a dryer, opt for a low heat setting. Avoid bleach and fabric softeners: Bleach can damage the fibers and alter the fabric's color. Fabric softeners are generally unnecessary and can actually make organic cotton less soft over time. Iron with care: If ironing is necessary, use a low heat setting or steam to remove wrinkles. Store properly: Fold and store your garments in a cool, dry place to maintain their original softness and structure.
