The innovative Cool Grip construction uses specially-designed fins to keep your fingers protected from the heat of your drink—and the rigid rim keeps it sturdy and easy to drink out of. At a generous 480ml, the Cool Grip X-Mug holds almost double the volume of our X-Cup (250ml). And the Cool Grip X-Tumbler holds 350ml—the perfect size for a beer, soda, wine or mixed drink at the end of a long hike. When you’ve drained the last drop, these collapsible cups can be packed away almost anywhere.
