Besides being a super shade of green, Snow Peak Single Wall 450 Mug is lightweight, virtually indestructable, and works both on and off the campsite. Collapsible handle for easy packing, though surely they’d rather strap it to their bag, on full display. Double walled version available elsewhere. How to choose? This single-walled version can be used directly over a flame, the double cannot, but it keeps contents hotter longer. Maybe one of each?
FYI: a lid is available separately for this cup too. +/-$5
