New yeti Rambler Colster Tall 16 oz. size is a perfect fit for bigger cans (like craft beers), keeping the last sips as good as the first. 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 suns blazing.
