Thermal Properties

Guyot Designs: Single walled with no insulation, but you can cook in these bottles. Cannot be frozen or welds will break. Obviously the bottle will be very hot if you cook in it so use proper tools to handle bottle after heating.

Klean Kanteen: Single walled with no insulation, but neoprene sleeves are available. Cannot be frozen or welds will break. Can heat over flame in a pinch but smaller top means heating will be uneven. Obviously the bottle will be very hot if you cook in it so use proper tools to handle bottle after heating.
