The Sea to Summit compact X-Cup is perfect for smaller hands or just smaller amounts. It's constructed from a flexible, food-grade silicone that collapses down to save room in your pack.


  • Flexible, food-grade silicone walls collapse, slimming the cup down to a slender 0.5 in. thick and minimizing the space it takes up in your pack
  • Rigid ring within the rim keeps it sturdy and easy to drink out of
  • When collapsed, X-Cup 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 cup 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
  • Holds 8.3 fl. oz.
  • Sea To Summit X-Cup dishwasher- and microwave-safe
