Should have said if you make a cosy it will put your packed weight up very slightly BUT it will save you a lot more weight in fuel.

I made the mistake of buying some cheap dehydrated food on the last trip, instructions said allow 7 mins to rehydrate the food, left it 45 mins and it as still like eating bullets.
Point is i boiled the water, filled up the packet, turned down the open end and placed it in a cosy i made in the shape of a envelope.
Even after 45mins is was still hot enough to burn your mouth.
The cosy weighs 39g

Don't want to go off topic but if you want details on the cosy just let me know.


Should also have said that IF you're going in the colder months and IF you do decide to use a adaptor be careful on the gas canisters you choose.
Butane does not perform well in cold conditions as it has poor vaporisation at low temperatures.
Propane is better but the containers tend to be heavier as it's stored pressures are higher.

Most brands have a propane/butane mix, in colder temps you want to be looking for a higher propane content.

One other thing if you choose a remote stove then as i'm sure you already know in colder temps the gas canisters work better upside down.
What you might not know is that in cold weather it's important to use the canister upside down EVERY time you use it.
If you use it the right way up then you are burning off the gasses first (as opposed to in a liquid state upside down) so you will burn off all the Propane first if you use it right way up (in cold conditions) leaving a nearly full canister of pretty much useless (in cold weather) butane.

As you'd buy your gas on route if you went with a gas burner this is unlikely to be a problem, but it is good to know.

That's really useful info about the gas in cold weather, thanks. It's not something I was aware of because it was the problems with gas in cold weather that made me shift to liquid fuels, originally an ancient paraffin Primus stove that I was given and which did sterling service for many years and I've used liquid fuels ever since.

I'd be interested in your instructions to make a cosy, new thread perhaps?

since its got onto msr stoves

i'v used my dragonfly an awful lot, including four months as the only stove for two of us in base camp. mostly on petrol (we used about a gallon a fortnight) with an odd can of coleman fuel for cleaning

when on the move i'v often just bunged a random motorist a fiver for a fill up from there petrol can...ok its dearer than a petrol station but you'd be surprised how easy it is to get a refill

to be fair though i'v never liked the plastic pump and often wondered if a primos pump could be modded to fit

I like a morning brew, usually porridge for breakfast and a hot drink or two with my evening meal which will be dehydrated meals. This means I am boiling a minimum of 500-600ml of water at a time.

I am a big fan of alcohol stoves, I've got 10+ but the minimum amount of fuel I have used to boil 500ml is 20ml in perfect conditions. For my usage that is a minimum of 40-50g of fuel a day with the stove weighing 8g (cat stove) to 45g for a whitebox, plus say 30g for the fuel bottle; so a very minimum for a 2 day trip of 118g in absolutely perfect conditions, say 150g allowing for less efficient combustion, preheat etc. However a FULL 100g gas cartridge weighs 190g and my gas stove weighs 45g so a total of 235g, less if the cartridge is not full; meaning the difference is a mere 85g (a 3m household tape measure weighs about that) and bear in mind that the gas option will do a 4-5 day trip.

So even for a 2 day trip gas is a very strong contender and for 3 days or more is actually a clear winner. However, if your style of eating/drinking doesn't require many hot drinks/meals then alcohol makes more sense for short trips/more cold meals.

Planning fuel consumption in fine detail is destined to end in tears, as many have found out the hard way in a Scottish winter.

When going overseas, I would seriously advise to travel without a stove and source one at your destination, it's what I've personally done for over a decade so nobody can tell me that it won't work, you make it work because that is part and parcel of your ability to survive the trip.

How do the local population live there?

What fuel do they use?

Burn that.

What do they drink?

Drink that.

What do they eat?

Eat that.

I may be wrong but in the UK the butane/propane mix canisters are standardised, all the same. In the winter go for a tri fuel mix, the butane/propane/isobutane canisters.

Canisters do work better in cold weather upside down but you should really only do this with stoves that have a preheat tube running over the burner head or you will risk some major flare ups so use caution.

I can't hike anymore but if I could I'd use one of my Primus Omnifuel stoves which will burn paraffin/naptha/coleman/panel wipe/Aspen 4T/petrol (dirty fuel)/diesel (another dirty fuel) and standard thread gas canisters. They boil fast and simmer well.

That's correct Rik; Europe now uses standardized EN spec cartridges. Most are tri fuel and will down below freezing comfortably, branded Jetboil fuel will go to -12c.

What about nitro fuel that goes in them little RC cars

This is used in 2 stroke engines so has a premix with oil as well (different ratios depending on the car/engine) so it burns very dirty

I'd be interested in your instructions to make a cosy, new thread perhaps?

Yep i'm happy to do that

Just took a look through my canisters.
The Primus Power cartriges are tri mix, i have several Coleman canisters that are labelled as 70% Butane, 30% Propane.
Have several other brands that have varying mixtures, a Greek made "Camper gaz" is labelled as 100% Butane.

So although there might be stronger regulation in the UK i think it's worth checking the canisters once you're buying cartridges outside the UK, just to be sure.

Good spot on pre heat tube and flaring up mate, thanks for picking that up.

I have seen videos in the cold where the cannister has been kept cold, using a sol ti, and once the propane is boiled off they fail at -5c temps. In the video the fella produced a new cartridge and the propane boiled the cup.

I don't know about the regulators on em, but it seems they don't manage well at the above temprature. Liquid feed to keep the propane in the cannister.

As for the fuel to be going long distances with, how much do you cook ?

Not too sure what your point is mate?

ALL upright gas canister burners have exactly the same problem, it's not really a Jetboil specific problem.
Personally i don't camp out at anything near freezing very often, so it's of little consequence to me, but it is a well known and well documented flaw with upright gas burners.

There are bodges you can do like stand the cartridge in warm water, or very very very cautiously use a heat shield to reflect some heat from the burner back into the cartridge.

If i do want to cook at really cold temps i just take my Kovea Spider as it's a remote burner with pre-heat tube.

With regard to Jetboil regulators, in my experience the SOL burner is the one to get, it's more efficient and has better control than the burner used on the other systems.

Have to say i am a really really really begrudging Jetboil user, i was absolutely disgusted at the their terrible after sales support when my Ti cup heat exchanger melted.
They agreed to exchange it till i told them i was in Europe then effectively told me there is no warranty on European sold Jetboils.

The manual when i bought the stove said anything with a high fluid content could be cooked, but then changed all documentation after serveral other exact same failures so now it says it's ONLY for boiling water.

Disgusting and deceitful in my opinion and i'd never buy another Jetboil product BUT for only boiling water and for it's weight and efficiency there is nothing that comes close to the Jetboil SOL Ti for anything above freezing temps.

I've never come across fuel issues abroad? Going across to Europe normally means I'll pack my primus and fuel bottle but will also take screw in gas canisters. Even in the Philippines last year responding to Haiyan, meths was still available alongside the local moonshine

That's very weird, i've travelled extensively and never had any problems finding threaded type gas cartridges.

If you're travelling through France there are hundreds of decathalon stores around the country they all stock threaded gas canisters.
http://www.decathlon.fr/cartouche-power-gas-100-g-id_8185223.html

So, as I change trains from Gare Du Nord to Montparnasse where is my nearest decathlon?

What about the change of trains at Toulouse-Matabiau? Arrival at L'Hospitalet-près-l'Andorre ?

Upon arriving in Seyðisfjörður where is my nearest source of the correct gas cart? What about Torshavn?

As i say personally i've always found threaded cartridges pretty easily, but if you are nervous about finding them then you could take an adaptor.
This one allows you to use the gas canisters that are used to fill up lighters, most news agents will sell this type of canister.

Alternatively there are the type that convert a pierced type canister to a threaded type
In many European countries the vast vast majority of supermarkets sell these types of canisters.

Do they? Never seen them in AH when I lived in the Netherlands...

Can't say as i understand your concern about gas canister stability.
Any stove you use needs to be on level ground, your Whisperlite has a smaller footprint than the feet that come with Jetboils.
In all my years using gas canister stoves i can honestly say i've never had one topple over.
So i think you are over thinking it.

Footprint vs centre of gravity.

Likewise i think you are over thinking the weight thing.
Your Whisperlite weighs in around 410g packed, add to that say 850g for fuel, that's 1260g

We've already concluded your equivalent gas canisters will be 373g

A Kovea camp 5 remote stove weighs 142g as a comparison, my Kovea spider is only 195g still more than 1/2 the weight of your Whisperlite.

Whisperlite with fuel = 1260g
Kovea spider with fuel = 568g

If you really want to get anal about weight take a look at the Fire-Maple canister top stove at 49g.
Fire-Maple stove 49g + plastic canister feet 29g = 78g and this is as stable as any stove i've used.

But if I leave the whisperlite at home and take the fire maple vortex, at 227.2 grams. OOI, how did you derive the 850g of fuel? Please can you show your working.

Alternatively if your just boiling water take a look at the Jetboil stove range.
Had problems with my first generation Sol Ti, the heat exchanger fins melted while i was cooking beans.
Bought a second cup and have been using that JUST to boil water for over a year without any problems.
The burner, plastic spreader feet, cosy and 800ml cup weigh only 344g

I investigated the jetboil range, discounted it for gas and also seemed like a one trick pony to me.

As i say i wouldn't recommend it is you plan on cooking, but for just boiling water it's extremely efficient, extremely fast and extremely light.
373g for you gas canister and 344g for the Jetboil and you have your complete cooking system for around 2 weeks for 717g.
I can get lighter, but then i have to start using smaller cups/pots and this starts getting a pain when cooking.

You can get extremely light if you want to. But it's actually the best trade off of fuel availability, energy density, durability, controlability, and ease of use. It's a massive set of simultaneous equations, and I am trying to find the answer of best fit.

I've spent the last 25 years working and living in austere conditions worldwide and I've rarely given the subject that much thought.

Isn't the whole point of bush skills the ability to just get on with it using whatever is available?

I am well and truly sold on pot cosys. Brilliant idea. Will be using them as standard.

I made the mistake of buying some cheap dehydrated food on the last trip, instructions said allow 7 mins to rehydrate the food, left it 45 mins and it as still like eating bullets.
Point is i boiled the water, filled up the packet, turned down the open end and placed it in a cosy i made in the shape of a envelope.

Podcast bob has kindly made a video:

https://www.youtube.com/watch?v=VkQA0_duIHE

I have a couple of cosy pouches that I use to transport my food on lowland trips, this weekend I am putting sausages in them that I have frozen, so that by the time I wake on Saturday they are about ready to cook but not too hot.
Should also have said that IF you're going in the colder months and IF you do decide to use a adaptor be careful on the gas canisters you choose.
Butane does not perform well in cold conditions as it has poor vaporisation at low temperatures.

As you'd buy your gas on route if you went with a gas burner this is unlikely to be a problem, but it is good to know.

the inverting the gas cart is hard if you have a stove mounted burner tho, so you then get the remote cart stoves, which are heavier, and approaching the weights of the petrol stoves.

I'd be interested in your instructions to make a cosy, new thread perhaps?

See video linked to above.

since its got onto msr stoves

i'v used my dragonfly an awful lot, including four months as the only stove for two of us in base camp. mostly on petrol (we used about a gallon a fortnight) with an odd can of coleman fuel for cleaning

when on the move i'v often just bunged a random motorist a fiver for a fill up from there petrol can...ok its dearer than a petrol station but you'd be surprised how easy it is to get a refill

to be fair though i'v never liked the plastic pump and often wondered if a primos pump could be modded to fit

When I was in slovakia I actually siphoned some petrol out of a friends car fuel tank in order to be able to cook dinner. Lesson learned: Petrol tastes horrible.

On this trip one of the people I was with had a jerry can of diesel, wish I'd had a stove that could burn it.

Having read the entire thread now ive got confused, are we talking about carrying all the fuel from the beginning of the trip or refilling a 1L bottle as we go along?

That depends on the fuel choice, and it's availability. The ideal would be to carry enough to get me from one settlement to the next and then refuel. But, as some settlements have hotels, but not petrol stations or shops, it may be necessary to carry the fuel the whole trip. It depends.

I like a morning brew, usually porridge for breakfast and a hot drink or two with my evening meal which will be dehydrated meals. This means I am boiling a minimum of 500-600ml of water at a time.

For me it's a cup of tea with breakfast, maybe one for lunch, hot chocolate in the evening, plus dinner. Each is 250ml or so.

I am a big fan of alcohol stoves, I've got 10+ but the minimum amount of fuel I have used to boil 500ml is 20ml in perfect conditions. For my usage that is a minimum of 40-50g of fuel a day with the stove weighing 8g (cat stove) to 45g for a whitebox, plus say 30g for the fuel bottle; so a very minimum for a 2 day trip of 118g in absolutely perfect conditions, say 150g allowing for less efficient combustion, preheat etc. However a FULL 100g gas cartridge weighs 190g and my gas stove weighs 45g so a total of 235g, less if the cartridge is not full; meaning the difference is a mere 85g (a 3m household tape measure weighs about that) and bear in mind that the gas option will do a 4-5 day trip.

I was amazed at how much fuel my cat can stove goes through to make a cup of tea. Most disappointed.

So even for a 2 day trip gas is a very strong contender and for 3 days or more is actually a clear winner. However, if your style of eating/drinking doesn't require many hot drinks/meals then alcohol makes more sense for short trips/more cold meals.

Yep, the maths on paper clearly come out in favour of gas stoves. *BUT* would you risk not being able to get the fuel for it?

Planning fuel consumption in fine detail is destined to end in tears, as many have found out the hard way in a Scottish winter.

When going overseas, I would seriously advise to travel without a stove and source one at your destination, it's what I've personally done for over a decade so nobody can tell me that it won't work, you make it work because that is part and parcel of your ability to survive the trip.

That entirely depends on a number of factors, primarily:

- Where you are going
- What stoves they have available.

It's all well and good to say to use what the locals use, but do the locals actually climb up mountains or, walk for 14 days in the wilderness? Are their stoves the lightest most rugged bits of kit that you are happy to put in your pack and carry for said distance?

How do the local population live there?

What fuel do they use?

Burn that.

What do they drink?

Drink that.

What do they eat?

Eat that.

Again, do they carry it on their backs for 14 days? It's the difference between wilderness travel and being a tourist.

Would you carry a sack of charcoal and a cast iron braiser even 1km, let alone 300?


I may be wrong but in the UK the butane/propane mix canisters are standardised, all the same. In the winter go for a tri fuel mix, the butane/propane/isobutane canisters.

I love the amount of safety warnings that gas comes with, it feels like more than any other form of fuel, but that may be my own bias away from gas.

That's correct Rik; Europe now uses standardized EN spec cartridges. Most are tri fuel and will down below freezing comfortably, branded Jetboil fuel will go to -12c.

Groovy, two questions: what is the EN standard number? and when did it come in to effect?

I've never come across fuel issues abroad? Going across to Europe normally means I'll pack my primus and fuel bottle but will also take screw in gas canisters. Even in the Philippines last year responding to Haiyan, meths was still available alongside the local moonshine

I have. I found myself with a petrol stove surrounded by diesel vehicles. I've been with friends who couldn't get a gas cart.

Could your trips not supplement between open fire cooking and stove use?

That would require me to carry different pots to the ones I may use on the top of the stove, the heat proofness on the handles of my evernew pots would not fair well on the fire I fear. Also see the previous statement about going days without seeing a tree. Burning anything smaller is going to be inefficient in an open fire config and thus something like the ever new DX stand or the pocket stand would be required to make efficient use of the biomass.

I've spent the last 25 years working and living in austere conditions worldwide and I've rarely given the subject that much thought.

Interesting, what is your prefered method of cooking in such circumstances? And when you say austere conditions, are the same as "in the middle of nowhere?"

Isn't the whole point of bush skills the ability to just get on with it using whatever is available?

Yes. But what is available is not always the same. You can try to make a fire on the side of a mountain using the rocks, or you could carry a stove and fuel up there with you...

Where are you thinking of going?

From post 28 in this thread:

"It's all very much at the planning stage, so don't want to say too much until I've at least narrowed the list down more."

Tho I'm sure people can guess some of my destination choices from the comments I've made through the thread.
