These classic white dad caps are super easy to use. Just put them on your head and you're good to go! They're perfect for casual outings or any sunny day. When it comes to maintenance, you can spot - clean them with a mild detergent if they get dirty. Just be gentle so you don't damage the fabric. Remember, because of the California Proposition 65 warning, avoid long - term direct contact with the cap's inner parts if you're concerned about the chemicals. Keep them in a dry place when not in use to maintain their shape and color.
