The REI salesperson said that the 8 oz canister has a 3-hour burn time. I doubt this is correct for my application, My experience was about 10 minutes/day (total) for 7 days = 70 minutes. Possibly 3 hours on a very low setting.I used this with an original Jetboil stove on an 8 day trip (7 full days of stove use). Summer trip (34-72 degrees ambient temperature range at breakfast/dinner) at 7,600-8,900 ft elevation. For 2 people, we boiled 0.4-0.5 L in the morning, and 0.5-0.8 L in the evenings. The 8 ounce canister lasted the fill 7 days ...but the pressure was getting low. Note: I did not try to warm the canister to increase pressure.The "float" gauge printed on the side of the canister was helpful, but was difficult to determine when the fuel was getting ... MoreThe REI salesperson said that the 8 oz canister has a 3-hour burn time.

Week trip =8 oz, Longer or larger group = 8 oz.

Bought this particular size because it was the least expensive at the time.Most isobutane canister brands perform more or less the same but it being from MSR you know your getting the real deal.As for the size, I like mixing it up so at home I have a stash of canisters of all different dimensions and pick and choose what size I need depending on the adventure.But whatever the canister brand or size you choose, the most important thing is the stove you use. Don’t go cheap. Do your homework and go for quality. Get a stove with a pressure regulator and integrated windscreen (MSR pocket rocket deluxe, Soto WindMaster…). You will save on fuel and the cooking/boiling will be much more enjoyable.I also like using a Snowpeak mini flame. I keep my almost empty canisters ... MoreBought this particular size because it was the least expensive at the time.Most isobutane canister brands perform more or less the same but it being from MSR you know your getting the real deal.As for the size, I like mixing it up so at home I have a stash of canisters of all different dimensions and pick and choose what size I need depending on the adventure.But whatever the canister brand or size you choose, the most important thing is the stove you use.

I keep my almost empty canisters for my mini flame that way I use up all of the fuel. The mini flame does not require much gas to operate and it creates a nice ambiance.

MSR Isopro 16 oz. 450G Canister it will last several days for boiling water and cooking food in higher altitude. Just keep in mind that altitude will actually make boiling time faster. As you ascend, atmospheric pressure decreases and shortens boiling times for all liquids. However, above 8000 feet you will need an stove with a pressure regulator like the MSR Pocket Rocket Deluxe camp stove to perform properly. MSR Isopro fuel canister will perform great in higher altitude and colder weather as well. No matter what size MSR Isopro you may carry in your back pack but, they all perform as good as each other. I personally carry MSR Isopro 16 oz. 450G Canister in my backpack as always. Not only it works way last longer than other size canister but also price is much ... MoreMSR Isopro 16 oz. 450G Canister it will last several days for boiling water and cooking food in higher altitude.

Pros:- Small bottle is good for a overnight backpacking trip in the summer/fall. Enough fuel for boiling water for 2 people for dinner/breakfast.- Bottle is smaller than other brands so do not have to carry extra weight.- Works well with my soto windmaster stoveCons:- Not really good for winter in ontario. On a -7 degree celcius day (with a low wind chill) in algonquin provincial park in mid-december, the fuel does not stay lit. After warming it up in the yurt we were staying in, it only stayed lit for a few minutes.
So, after 4 group trips I think I have a number for how much fuel to bring, and by fuel I mean the iso-pro canisters. My trips have been at about 5700', 8000', and 10000'. Evening temps in mid 40's F, and morning lows in the high 20's to low 30's F. Your mileage may vary, and I encourage you to experiment yourself, but I found that 1 person burns about 1/12 of a pound (Again those imperial units!) a day just for the simple act of boiling water. That is hot water for oatmeal and coffee in the morning, and for re-hydrating de-hydrated meals for dinner. These were old school pots, lidded, and filled close enough to the top. Ambient temperature seems to be the most important factor. We are only boiling water, so that leads me to think, that we actually burn less fuel ... MoreSo, after 4 group trips I think I have a number for how much fuel to bring, and by fuel I mean the iso-pro canisters.

We are only boiling water, so that leads me to think, that we actually burn less fuel the higher up we go, as water boils at a lower temperature.These canisters always worked for us. A friend brought a Coleman pounder last September, and that thing wouldn't stay lit in cooler temps. It wasn't that cold, but only when it that canister was warm would it run. MSR always worked, and fortunately I had enough in my canister to last the week.
Bacpackers note that this is the large size. As with any long trip, weight is an issue although when it comes to cooking and safety, this is likely good weight to carry depending on access you have to additional supplies and if on a trek, get used to how long a container lasts generally as it is never fun to find you run out of gas. You can measure by weight at home, the immersion test (see youtube) or use one of the devices created by jetboil. Note this size will not fit cooking sets for stacking purposes which is usally on the smallest size. Also note that the unit may make your stove setup more unstable depending on the stove you have. Consider the tripod that may come with your stove but always ensure stability. This may not be great for some top heavy stoves ... MoreBacpackers note that this is the large size.

I cannot comment on cold weather perfromance but there are interesting articles on the internet on this issue and you should read them if you head out winter camping. I have not had a failure on this brand. The main issue is how long this size will last, cold weather performance and how the unit packs away for you. Final thought..i actually thought it was not "legal" to send this type of product through the delivery system ie pick up only but in fact Altitutude delivered. Curious about that though
Had purchased a few cans for a through hike in TX. Store was out of 8oz cans, so had to buy smaller capacity. It all worked out better than expected. I had an opportunity to discard empty cans a few days into the trip and returned unused ones once completed the hike. Happy with the service and quality of the product. Used it with whisperlite universal stove. Felt that consumption was slightly higher than expected, but that could be due to weather conditions, as was pretty damp.
MSR Isopro fuel is my choice for pressurized canisters as it’s proportionally mixed for cold weather high altitude use. I enjoy watching that pure blue flame when you’re cooking with gas. I purchased the large tall 16 oz for cooking outside the RV keeping the grease splatter and food odours outside. These are great for use as long as your car camping too large for hiking. Enjoy the great outdoors.
I have an Optimus crux lite stove and took a partially full Jet boil Jetpower canister and a MSR 3.9oz isopro as a backup on a 2night backpacking trip for 2 people. We were at 7500' and using the MSR in temps in high 20's to 40's. It was not windy. We calculate that the 3.9 oz MSR boiled only 5 liters of water and warmed 2 tortillas before running out. Luckily it was our last planned meal and the 2nd tortilla was mostly warm. Is that normal? It seems less than expected. It seems that the calculations are 1.6 to 1.8L per oz, but that should have resulted in 6.2 to 7.0 Liters. I'm sure altitude affects it but then the water boils at lower temps so...?? It may be just what is normal in those conditions and I should plan accordingly on future trips. * of note one of our ... MoreI have an Optimus crux lite stove and took a partially full Jet boil Jetpower canister and a MSR 3.9oz isopro as a backup on a 2night backpacking trip for 2 people.

One can, have gone camping two weekends, two people. Daily making coffee, oatmeal, noodles. haven't taken the times of cooking, since they say it can last up to 3hrs under certain conditions. I think i'm already at 2 hours with my first can. I have another one ready but this one just won't quit lolUsing it with an MSR PocketRocket 2 Stove, morning was around 12 Celsius when making breakfast.It's small and fits nice inside my cooking pot, which fits nicely in my backpack.
