To use this cap, simply adjust the snapback closure to fit your head size. You can wear it in any casual or outdoor situation to cover your hair or add a trendy touch to your outfit. Remember, since these hats are made to order, you'll need to wait 7 - 10 business days for processing. When it comes to maintenance, you can gently spot - clean the polyester foam front panel with a mild detergent and a soft cloth. For the mesh back panels, a quick wipe with a damp cloth should do the trick. Avoid machine - washing or putting it in the dryer to keep the hat in good shape.
