Material & Craftsmanship Crafted from a high-performance Ice Silk fabric, this sun hat is engineered for superior comfort and protection on the warmest days. Ice Silk is not actual silk, but a scientific name for a modified viscose fiber known for its exceptional properties: Cooling Effect: The fabric has a high thermal conductivity, allowing it to absorb body heat and provide a cool, soothing sensation against your skin. Breathable & Moisture-Wicking: Its unique structure allows air to circulate freely while pulling moisture away from the skin, keeping you dry and comfortable. Silky Smooth & Lightweight: The material is incredibly soft and light, preventing irritation and ensuring it's comfortable to wear all day long. UPF 50+ Sun Protection: The dense weave of the fabric provides an excellent barrier against harmful UVA and UVB rays, protecting your delicate facial skin. Care Guide (To Keep It Lovely Longer) Follow these simple steps to maintain the beauty and shape of your hat: Hand Wash Only: Spot clean with a damp cloth or hand wash in cool water with a gentle, neutral detergent. Do Not Wring: After washing, gently squeeze out excess water without twisting or wringing the fabric, as this can damage the fibers and shape. Reshape and Air Dry: Reshape the hat to its original form while it is still damp. Lay it flat or place it over a rounded object (like a bowl) to dry. Keep it out of direct sunlight to prevent fading. Avoid Heat: Never use a tumble dryer, hairdryer, or iron on the hat, as high heat can damage the material.
