The one thing I don't like about the MEC product is the kind of rounded bottom. Sigg makes stainless steel bottles with a bit more of a squared off bottom,
Sigg Water Bottle. The one shown in this link is .6L but they make them in .75L and 1L sizes as well. I hadn't seen this one before, but Sigg also makes a stainless steel
Canteen with cup. Might be nice to be able to boil a second round of water while you drink soup or hot chocolate from the cup.
