Sea To Summit Collapsible X-Tumbler W/ Cool Grip

The Cool Grip X-Tumbler™ was built to keep your hands cool when drinking hot liquids. This is made possible by the unique Cool Grip design that reduces surface temperatures and heat transfer, allowing you to hold your hot tea and coffee firmly, without burning your fingers.
