We Love all Veranda covers . This canvas used to make covers is very sturdy and yet breaths protecting item covered . Perfect product to use as specified and may also be used for anything that fits under cover. It worked perfect for my air conditioner , slightly snug but great product! . Right now I have All our outdoor pillows in another zip bag made by veranda product 
Great well made product. Make sure you measure Before purchasing for air conditioner or anything you will be covering .
