This bottle keeps it hot - Stanley Adventure Vacuum Bottle

All vacuum flasks are not created equal! I have been working my way through (metal-stainless steel) vacuum flasks looking for one that actually kept water hot for more than 6 hors. That seems to be the standard. Whether it is because of the plastic top that lets the heat out, the construction thickness, quality of manufacture - i don't know. But good brands and good looking bottles all performed the same. Then I bought this Stanley Adventure vacuum bottle, 24-hours later the water is still boiling hot. It is heavy, more car camping than backpacking. But if you want a bottle that does what it says keeps water hot for 24 hours this is it.
