With any velcro garments it is important to ensure that when the garment is not in use, the velcro is fastened. If the velcro is left open it can attract dust, fluff, lint and debris that will stop it from functioning properly. Over time if debris continually gets caught inside it can damage the velcro hooks.
Always ensure that the velcro tabs are fastened before washing. If machine washing your velcro garment, ensure it is in a wash bag to prevent it from snagging on other garments in the wash or collecting lint. Otherwise, please hand wash the velco garment separately.
