Sorry, this is a little off-topic. REI sez it'll have stainless wide-mouth 32-oz Nalgene bottles in April. While these may not be the lightest, can they be used to heat water, even directly on a fire, and thereby replace a pot? You could also flavor your water and not have to worry about the plastic absorbing an odor, n'est-ce pas?
Thanks in advance for any insight...
