Improved X-mug.


  • Improved grip
  • Ease of hand-holding very hot liquids
  • Compact/collapsible, lightweight, and affordable
  • Convenient


  • None for me

I reviewed the Sea-to-Summit X-mug several years ago and liked it what it offered. Lightweight, compactness, affordability, and convenience.

This updated version now has small nubs on the outside that make it easier to grip, and better able to hold very hot liquids without overheating the fingers. The weight and dimensions are essentially the same. A worthwhile improvement.


Used its predecessor for several years, and the new one on several trips so far.
