Wallaroos Victoria Diva has a durable design. We recommend handwashing your hat in cold water with a gentle soap to safely remove any residue, dirt or grime from the poly-straw weave. Stuff the crown of your Victoria Diva with kitchen towels to air dry, brim down. If your hat looses a little shape, steam it as necessary. Do not use a hair dryer to speed up the drying process. To maintain optimal shape recommends packing by stuffing it.
