YETI's Rambler 16 oz. Colster Tall Can Insulator size is a perfect fit for tall boys (like our Lake of Bays cans!), keeping the last sips as good as the first. Their 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. at all costs.
