That is the oversized Sierra cup on steroids. The classic cup is about half that capacity. I fashioned a lid for my cup - take a piece of aluminum and cut away everything that doesn't look like a lid.

Actually, I wish there were a source for a snap-on lid for the S cup. It would be much more useful that way.

The "pot" in the mini-Trangia cookset is also about 750ml. It is my favorite solo cookset. It can always work as a cup, as well, but I prefer a separate cup, usually.

The sierra cup/bowl is a classic, versatile design which is fairly light weight. It also works as a shovel if you need to dig for water in a desert stream bed. I suppose you could even fry bacon in it....
