Hi folks,
Been lurking for awhile now and wanted to say thanks for all the great info I've picked up here.

I have one of these bottles and they are great. The cup however seems to be double walled. I had thought to use it for boiling too, but I don't think it will work too well.
The cup and the bottle are very substantial and I'll probably pick up a few more just because I like the shape much better than the round ones. They look cool too.
I had seen what looked like the original bottles and cups at one of the suplus dealers, but for the life of me I can't remember which one. I bet those cups were single walled.
Anyway, thanks again,
Steve
