It truly works for HOURS.
I routinely make coffee at 6am and have a nice hot cup at 1 in the afternoon. I say its cumbersome because with the first cap/cup in hand and thermos in the other, there's still the second cap to get off. If you have a place to set it down, you're golden.The interior is a highly polished metal, and doesn't seem to change the taste of the contents at all. The exterior is steel from what i can tell, and it takes a beating, but does add to the overall weight. However, after having kept soup warm for 6 hours on a winter summit in VT, this thing is worth its weight in gold to me.
