The Nissan Thermos bottle up there is good, but I am not sure about the other pictured or mentioned ones. When the cap lacks insulation, all the heat exchange flows through there. Can you open and close the bottle with one hand only? If you have hot liquid in the bottle will you burn your lips or not? Can you hold and shake the bottle upside down with no leak? A good bottle needs to meet all such check marks. Coloring is likely to rub off over time and make the bottle look repugnant while it rubs off.
