How do you carry water in your bug out bags? Personally, I like the US Military canteens. I have used them for many years without a problem. If you can still find them, the older stainless steel ones are my favorite, but the new plastic ones are functional. I avoid the aluminum ones; they always seem to be corroded.
The newer canteens come with a good sturdy cover and clips that can be attached to a large variety of belts or straps. The older ones were designed to only work with the pistol belt. A canteen cup and a stove will fit in the cover with the canteen. The cup is extremely handy and can be used for heating hot drinks or cooking. It is made of stainless steel.
The stove is designed to work with military heat tabs but can be used with a variety of fuels. I have used mine with small quantities of hot coals when the wind was blowing and been able to heat up drinks. There are some new commercial designs that claim they can be used with wood. I have not tried them so buy at your own risk.
If you take care of the military canteens, they will last for years. I have not found any civilian canteens that will outlast the military versions. When you go to purchase one, be sure to get a real US one and not a cheap knock off.
