Keep your fingers cool and your drink securely in your
grasp with our collapsible Cool Grip X-Mug and X-Tumbler.
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.
