Rambler Colsters

The 355 ml / 12 oz size is perfect for sparkling water, soft drinks, and cold beverages, all kept straight-from-the-cooler cold while kicking back on the boat, at camp, or wherever good times are going down.

The 473 ml / 16 oz. size is a perfect fit for bigger cans, keeping the last sips as good as the first. Our 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.

The 355 ml / 12 oz. slim design, ideal for keeping hard seltzers icy cold while hanging out on the hottest days. Double-wall vacuum insulation and No Sweat™ Design keep your hands dry, and the updated Load-and-Lock™ Gasket only requires an easy quarter-turn to secure your drink in place.
