The 16 oz. size is a perfect fit for bigger cans (like craft beers), keeping the last sips as good as the first. The new Load-and-Lock™ Gasket requires an easy quarter-turn to secure your drink in place. And just like the original, double-wall vacuum insulation is how your drink stays icy cold, so you can enjoy a cold craft brew even when the sun’s blazing. Resists dents and drops, double wall vacuum seal that keeps cold drinks cold, and dishwasher safe.
