Our 64 Oz Stainless Steel Trekkers' Growler allows the drinker to transport beer from place to place while keeping the beer's temperature and taste for up to 24 hours. Made of food grade 18/8 stainless steel, this is perfect for enjoying craft beer after a long hike in the mountains, going camping or to the beach, etc. A stainless steel growler will keep your beer cold and fresh longer than glass, and it will not break like a glass growler when dropped. Stainless steel growlers do not allow any sunlight to get into the container making skunking impossible. This item has a passivized interior to create a shell against corrosion and ensure the lifetime and durability of the product. The attached swing top lid provides a tight seal for long lasting freshness. BPA FREE, FDA certified
