A Bobble Bottle is a must for replenishable refreshment on the go, and these specially contoured ice cubes will chill your drink to perfection. With 14 cubes that are as easy to release from their soft-push tray as they are to drop into the bottle, it's a speedy and pleasant way to hydrate. A built-in reservoir prevents the tray from spilling and refreezing, and the stackable design makes it easier to store.
