I'm looking for something that will do all 3. I'm picturing a SP 700 mug with a screw top or something like a mason jar made from aluminum or titanium. I have a friend who carries an aluminum energy drink bottle with a screw top for water and he made a caldera cone for cooking with it, which I thought was brilliant. Since I use a steripen and want a wide mouth bottle, though, I can't copy his system. Anyone ideas out there?

I'm a Steripen user also. I have a system I've been working on. I'll post pictures later. The whole thing : water bottle/cookpot, fuel bottle/stove, pot/coffee mug/cooking epuiment storage, coozie, spoon, bic lighter, hand towel and windscreen weigh 6.5oz.

Please post some pictures when you get a chance, Adam.

I like simplicity...even over weight savings sometimes. The idea of a single vessel for both water carry and cooking seems great to me. Add a simple stove, lighter and spoon and you're ready to go for freezer bag meals. Maybe some kind of windscreen. I've never had a problem using clothing or sleep gear for a coozie, just gotta be mildly careful.

Brain,

I posted pics in the MYOG section. If you have any questions let me know.
You can use the energy drink can with a Platy bag with the top cut off and still come in under 2oz.

Here is the link to the post.

Well this almost fits the bill.

The system is not quite leak proof. It does have a silcone washer.

You'll be getting your water near where you camp? No need to carry water being that you are using the Steripen?

Lots of variety at bplite.com. Stop by and browse the threads in the different forums.

I use/own a wonderful all in one container. It is an old aluminum Ovaltine shaker. It is similar to a martini shaker, it has an air tight lid that doubles as a cup, it holds two cups of water, and it is extremely light weight. The downsides to it are that it is delicate, being made of thin aluminum, and the base is kind of narrow which might make it difficult to stand it on some stove tops.
I don't think it would be very good for a water bottle in the capacity that I'd be drinking from it, but it can hold water and you could use it to store extra water to transfer to a more practical water bottle or camelbak.

I have a windscreen that it sits in when I am using it with an alcohol stove, otherwise I just put the lid on, dig a small hole for it, then rake in some hot coals from the camp fire and settle it onto them. The thin aluminum body transfers heat very quickly and efficiently, the lid fits so well I can literally hold the container full of water, upside down with no spillage.

You can sometimes find them on eBay, usually for 15-20 dollars after shipping. I just searched for "Ovaltine shaker" and found several of them for sale. =)

A company called exotac makes a titanium water bottle that looks like the kleen kanteen. Expensive though.

Single walled metal. Aluminium or stainless. Go to a thrift shore and look at the many options.

The Vargo titanium water bottle does the job well. I can boil water easily using a alcohol stove or building a wooden fire around its base. But the mouth is not large enough for the steripen..

Well looky here, this just came out today http://www.vargooutdoors.com/Titanium-BOT-Bottle-Pot

"Stop carrying both a water bottle and cooking pot, the “BOT” is designed to be used as both. In typical backpacks the BOT fits nicely into the water bottle pocket for easy access whether you are drinking water or preparing a quick meal. The screw-top lid was designed to be turned upside-down for cooking and the temperature resistant O-ring won’t melt when exposed to high heat. The lid was designed to be pot-lifter friendly and easy to grip. Specs:

Capacity: 1.0 Liters (34 ounces)
Weight: 4.7 ounces (28.3 grams)
Dimensions: 6.5 L x 3.9 D inches (165 x 99 mm)

Somebody needs to make one of those out of aluminum for the same or less weight and $5. Their price is excessive.

I wonder if it really makes sense to combine a water storage container and a cookpot. Five ounces is an ounce more than my 1L cookpot and 1L water bottle combined, and the cookpot is valuable as a hard sided container for fragile or pointy things in the pack. For many people, the cookpot is the only hard-sided container they carry.

How would you like it to fall out of your pack pocket? And it means you have to clean your pot like crazy to use it for water. And better put it in the bear bag overnight.

"And better put it in the bear bag overnight."

You could leave it on the ground, and the bear could use it as a chew toy.

And try finding it after that . I think the true fans of titanium are those who don't really cook anything other than water or who have simmering stoves. I have a standing search for "used titanium". Hits every day of the year usually used once.

Good job. I use a double wall every day for coffee so I'm a believer in terms of heat retention. The obvious question is price point and utility vs contamination and cost.And hey, I love buying other people's regrets.

When I travel ultralight by bike, I cook, as I usually plan to get food in the late afternoons.
So this pot is the perfect mulit-use piece of gear
It will be great :
- to complement my 2l water bottle on the bike, and take that extra liter of water for the evening's drinks and cooking.
- to allow me to soak beans, pulses and lentils to shorten cooking times
- to serve as my main cooking pot, and be able to sauté, fry and stew, not just boil
with a reflextix cozy
- I'll be able to drink my morning coffee out of it, and even keep some warm for my first break (I expect similar performance to a thermos)
- I'll be able to finish cooking rice, lentils, beans, pasta by simply letting it sit in the cozy
- store a cold one, or food that needs refridgerating and not have to worry about it leaking all over my gear.
I'm going to get one to try this system out.

I made this container today:

Expanding on that idea id like to see an XXL- wide load version of that which could be used as a bear canister, cook kit, camp sink, snow shovel/sled, mountaineering helmet and dinner gong!...how cool would that be?
