The YETI Rambler 16oz Colster Tall Can Insulator is a great fit for bigger cans (like craft beers), keeping the last sips as good as the first. The new YETI® 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.
