Sea to Summit X-Mug

Sea to Summit


The Sea to Summit X-Mug is a collapsible mug that is also calibrated as a measuring cup. The flexible silicone sides collapse making this a small compact disc sized dinnerware piece that nests neatly with other X-Series dinnerware and X-Pots.  The Sea to Summit X-Mug is a space saving mug for life-saving beverages.


  • Flexible, food-grade silicone walls collapse, slimming the mug down to a slender 0.5 in. thick and minimizing the space it takes up in a pack
  • When collapsed, X-Mug fits snugly into the X-Bowl (sold separately) for a compact and convenient camp dining set
  • Flexible walls let you accurately pour liquid from the mug into another container; rigid, reinforced nylon ring keeps the rim sturdy for spill-free drinking
  • Internal gradient markings help you measure out the contents
  • Walls and base withstand hot liquids
  • Sea To Summit X-Mug is dishwasher safe
