Using the Sunday Afternoons Classic Brushline Bucket Hat is super easy. Just adjust the internal sizing system to fit your head comfortably. You can store your sunglasses in the dedicated holder when you're not using them. When you're out on an adventure, the hat's ventilation will keep you cool. As for care, if it gets dirty, gently wipe the water and stain - resistant fabric with a damp cloth. Avoid using harsh chemicals as they may damage the bluesign® certified material. When packing, simply fold it up; it's designed to pack easily for travel. Remember, the mesh part isn't rated for UPF, so try to keep it in the shade for maximum sun protection.
