Good General Use - Not Good for Drinking
Honestly, this isn't a great mug for what I purchased it for - drinking hot fluids. The single wall transmits way too much heat to my lips and to the outdoors, cooling the drink quickly.
It would be good as an ultralight cooking pot/multi use item, though.
So, if you're looking for a straight mug, go to the double-wall Snow Peak mug (which is FANTASTIC). If you're using it as an ultralight all-in-one, this will likely meet your needs.
