What's a good thermos type thing that'll hold about a large cup's worth of coffee? Must be able to be chucked in a messenger bag without leaking or making the contents of the flask taste weird (the cheap one I got from TK Maxx fails on both of these). Are the thermos stainless steel ones any good? Quite pricey.
The stainless steel ones are good but with the following caveat. Heat the flask thoroughly with boiling water before putting your coffee in, otherwise it takes away a lot of the heat of the contents. Once this has been done they work reasonably well.
