I've had many, many ultralight stuff sacks over the years. Just tried the Lightheart one, and I think it is my favorite. Perfectly made, quality stitching, quick & smooth open and close. One thing that surprised me: It is small and wide enough that when you plop it down, even empty, it "stands" - in spite of its negligible weight. So I'm thinking of using this one to carry my lunch, and getting a bigger one to carry my sleeping bag.
