Designed for the beer-lover in all of us, the Hydro Flask 64 oz. Insulated Stainless Steel Beer Growler allows you to transport your favorite brew (or any beverage!) and keep it as cold and refreshing as when it was poured. You’ll have plenty to share with friends (or not). Replacing the existing cap on all our Wide Mouth bottles, the new award-winning Flex Cap is the ideal combination of strength and flexibility. Designed for ultimate portability, we crafted every detail with easy-carry comfort in mind – and insulated it too– so you can go further, for longer, keeping your favorite beverage comfortably by your side.
