Sea To Summit X-Mug No Colour

The Sea To Summit X-Mug is constructed from a flexible, European standard-compliant, food-grade silicone. A rigid ring within the rim keeps 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! The X-Mug fits neatly into the X-Bowl and X-Plate and altogether the collapsed set is less than an inch thick.
