The Sea to Summit X-Mug is a collapsible hybrid comprised of a rigid ring within the rim to keep it sturdy to hold onto and easy to drink out of, but still allows the mug to be collapsed to a disk that will fit in the palm of your hand!

Constructed from flexible, European standard compliant, food grade silicone. The X-Mug fits neatly into the X-Bowl and X-Plate and altogether the collapsed set is less than an inch thick. BPA free.
