Can you take boiled water that's pretty close to 212F and pour it into a hydration pouch (Nalgene, MSR, Platypus, etc) without it melting? I plan on getting a 2 or 3 liter unit for my pack, and don't want to have to boil water, then let it completely cool down before pouring it into the bladder. I'll be getting a JetBoil 1.5 liter pot to do the boiling.

If heat and bladders don't mix, then how do you boil large-ish amounts of water in a relatively short period of time? Do you need some sort of reservoir that CAN take the heat to act as an intermediate between the pot and the hydration bladder?

It should be fine, especially if you let the water cool down for like 15-30 seconds. In fact you can even boil the water in a plastic hydration bladder, but you have to be very very careful, keeping it way up off the fire and heating it very slowly.

check the pouch ! some you will have to cool down, the platypus works well. I use a 2 lt. military canteen, works very very well.

I ONLY buy Camelbak. All others (maybe with a one or two exceptions) aren't developed for hard use, like for the military.

It is advertised on the Camelbak website that their bladders can take NEAR boiling water poured in, but I would never put that thing over a flame unless it was the ONLY thing I had and there were no small natural rock pools I could stick heated rocks in to boil the water... Definite last resort. Having a tool container to hold your water (let alone a pot to boil it in!!!) is almost as important as drinking the dang stuff!

Awesome! That's really good to know and makes the entire water purification process that much easier.

I'll make sure I let the water cool some before pouring it into the bladder!

Thanks guys!

Just a thought, but you can either dip the bottom of the pan in water to cool it down faster (hence cool the boiled water faster too) or transfer/pour it in another container (like a 1ltr camelbak better watter bottle!) which also will cool the water faster before you put it in your bladder.

If I had the time, I would filter/boil the water, let it cool as much as possible so you don't drink hot or even warm water because you use up energy to cool it down or heat it up if it is cooler than your body temp and then repeat to fill up your bladder.

Ah yes, very good thought about heat transfer. Since I'll be using a folding bucket that holds 10 liters, dipping the bottom of the pot will be easy and transfer heat from the boiled water to the water to be boiled - energy efficiency!! I do most of my backwoods hiking/camping in cool weather - fall/winter spring so the warm water will be good for me.

I love this site!

I just cant trust something as important as water to a rubber bladder. I only use nalgene bottles.

Kevin, I agree with you for the most part. Two Nalgene bottles are my primary water containers. But I also carry a 2 liter platypus and/or the 10 liter MSR bladder, depending on the occassion. Regardless of what type of container you use, I think it's dangerous to carry only one water container.

I was planning on two water bottles in the pockets of my pack, but in the winter, won't they freeze, even if not completely filled and subject to constant movement?
