Doesn't hold much, about a pint,and will stay warm for about 5 hours. Larger thermos could be used for an overnight, warming up in the morning in a Jet Boil.

Coffee is the first thing in the morning,or it's going to be a bad day. Instant is the first choice,sometimes not the best. Starbucks, folg ers
 

,and taster,s choice in that order. Perked or boiled is sometimes used if there is somewhere to dispose of the grounds.
