The Sea to Summit X-Mug is a collapsible camping mug 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 Sea to Summit X-Mug fits neatly into the X Bowl and X Plate and altogether the collapsed camping cookware set is less than an inch thick.
Folds flat for compact packing
Food grade flexible silicone sides
Nylon ring at the top maintains shape & prevents scalded finger tips
