|With Mulholland's roots near the heart of California's premier wine region it was only fitting that a collection of travel wine bags , be designed to meet the needs of the wine connoisseur. All bags come with a semi rigid insulated nylon liner designed to keep chilled wine or champagne at temperature and to protect red wines from temperature extremes. This is the only bag for carrying wine to a picnic or traveling across continents. All wine bags are equipped with a carrying handle and padded shoulder strap. The 6 bottle rolling wine carrier has a telescoping handle and was developed for wineries and serious oenophiles.
