The classic gas canister, nested inside a titanium pot or cup with a small folding gas stove stored on top, has long been the gold-standard cooking set-up for hikers, mountaineers and trail runners.

Even with the rise of systems like Jetboil, it remains the go-to option for many serious outdoors people. When we're not using one of our own titanium nesting stoves, this is the set-up we reach for.

After plenty of cold, windy meals on the side of mountains, we kept tweaking both the gear we carried in our cook kit, along with the way it all packed together, making small changes until everything we needed had its place.

Originally, we carried everything inside a DIY bag we made for ourselves. After plenty of use, testing and small improvements, we decided to bring that design to market.

The bag, along with the other components we've designed, is built to improve the way this system packs, carries, stores and performs.

We don't manufacture the gas canisters or folding gas stoves themselves, but we'll include our stove recommendations below.

Any products in the Peak Limits range purchased alongside our gas stove bags are available with 15% off. The discount is automatically applied at checkout.

The Complete Set-Up Explained

What Makes Up the Full System?

This set-up is built around three main components: a gas canister, usually either 110g or 230g (approx. 3.9oz / 8.1oz), depending on trip length, a titanium cup or pot, and a small folding gas stove.

The gas canister nests inside the cup / pot, leaving some space around the edges for a roll-up wind-shield, and some space on top for the mini gas stove and a few other essentials.

Core Components (Stored Inside the Pot/Cup)

  • 110g / 230g gas canister (approx. 3.9oz / 8.1oz)
  • 750ml / 900ml titanium pot or cup (approx. 25oz / 30oz)
  • Small folding gas stove
  • Lighter
  • Pot/cup lid
  • FF Titanium windshield

Additional Kit We Carry (In Our Storage Bags)

  • Cleaning and drying cloth
  • Titanium spork
  • Water purification tablets
  • Tea, coffee and UHT milk sachets
  • Small gas canister stabiliser (sometimes)
  • FF Millbank Bag
  • FF Insulating Gas Canister Mat

Aside from the food and water itself, and a water filter (Grayl / LifeStraw), this set-up contains all of the cooking, drinking, and water-related kit we take into the mountains for multiple days at a time, the longest we've done being six days.

The Main Benefits of This Cook System:

One of the main benefits is this system's packability. The gas canister and cup/pot are usually the bulkiest parts of any gas cooking system, so being able to store these together saves a huge amount of space inside your pack.

Storing the canister inside the cup/pot also gives it some extra protection from bumps and knocks.

The 750ml or 900ml cup used to nest the canister is large enough for cooking, making coffee, and eating from, removing the need to carry a separate bowl or drinking cup.

The core components in this system are lightweight by design. A titanium cup/pot and a small folding gas stove are already among the lightest options available, keeping the weight of the complete set-up to an absolute minimum.

Although this set-up won't beat a Jetboil's boil times, it is still more than quick enough for most trips. A good folding gas stove paired with a 110g or 230g gas canister can boil water quickly, making it ideal for hot drinks, dehydrated meals, and simple camp cooking.

For most hikers, the small difference in boil time or fuel efficiency is outweighed by the extra flexibility, lower cost, and ability to use different pots and accessories. In our experience, when pairing this set-up with a quality windshield, the difference in boil time is pretty unnoticeable.

One of the biggest advantages of this type of system is that you are not locked into one fixed set-up. You can swap between different cup or pot sizes, use different folding gas stoves, carry a frying pan, change utensils, or adjust the kit depending on the trip.

For solo trips, a 750ml cup and 110g gas canister may be enough. For longer trips, or when cooking for more than one person, the same system can be built around a larger pot. It also gives you more freedom when it comes to actual cooking, rather than just boiling water for dehydrated meals.

The reliability of this set-up is mainly dependent on the stove you choose, as this is the only component where there is really a chance of something going wrong.

That said, simple folding gas stoves, whether inexpensive models or more premium options from brands such as MSR or Soto, have always been solid for us. They are simple, proven, and easy to replace if needed.

Another benefit is that you are not relying on one fully integrated system. If one part breaks, wears out, or no longer suits your needs, you can replace that individual component rather than replacing the whole cook system.

Because the cup or pot is titanium, it can also be used over a fire or wood stove if needed. This gives the system a useful backup option if you run out of gas, or damage your stove on the trail.

This is one of the biggest advantages over some integrated aluminium stove pots, which are designed specifically for one burner and are not always suitable for use over an open flame.

Another advantage is that you can upgrade the individual parts as needed, starting with a budget stove. If you opt for a cheaper stove, the costs compared to a Jetboil or similar integrated system are significantly less, but with far more flexibility.

Even with the gas canister nested inside the cup/pot, there is still useful space for smaller cook kit essentials such as a lighter, cloth, spork, tea, coffee, UHT milk sachets, or water purification tablets. Coupled with the FF storage bag, these smaller items can be kept together in one compact, organised, and easy-to-access set-up.

How Does This Set-Up Compare to Jetboil Stoves?

Admittedly, I have a slightly biased opinion when it comes to Jetboil stoves, after having the ignition system stop working on a hiking trip. That is not to say they are not a great piece of kit. They are fast, efficient, and excellent at boiling water quickly.

That said, we prefer the flexibility of a modular cup, canister, and folding stove set-up for the reasons below:

The modular cup, canister, and folding stove set-up has a real advantage when it comes to tailoring the system to different trip lengths and group sizes.

For solo trips, a 750ml cup and 110g gas canister may be all that's needed, whereas longer trips may justify stepping up to a 900ml pot and 230g canister. In most cases, all that changes is the pot size.

With smaller Jetboil systems, such as the Flash or Zip, larger gas canisters can still be used, but they often no longer nest neatly inside the pot alongside the burner and accessories. As a result, much of the packability advantage is lost when moving to larger canisters, often pushing you towards a larger Jetboil model if you want to maintain the same compact, all-in-one nesting design.

With a modular system, the same stove can be used across different pot sizes and canister combinations without needing to own multiple integrated cooking systems.

The modular system allows the use of a wide range of pots and pans, whereas Jetboil-style systems are primarily designed around their own integrated cooking vessel.

This makes the system far more versatile for actual cooking, rather than simply boiling water for dehydrated meals.

Because the cup or pot is titanium, it can also be used over a fire or wood stove if needed. This provides a useful backup option if you run out of gas or damage your stove on the trail.

Jetboil-style systems are excellent for fast boil times, and this is one of their main advantages. However, small folding gas stoves are still very capable.

In our experience, when boiling around 750ml of water with a good windshield, the Jetboil is only around one minute faster. For most trips, that small saving does not outweigh the extra cost, reduced flexibility, and limited cooking options.

A good folding gas stove is still more than quick enough for hot drinks, dehydrated meals, and simple camp cooking.

Another advantage is cost. You can start with a budget stove and upgrade individual parts over time, creating a cheaper set-up with more flexibility.

If one part breaks, wears out, or no longer suits your needs, you can simply replace or upgrade that component rather than buying an entirely new cooking system.

There is also the option to upgrade to more capable stoves, such as the MSR PocketRocket or Soto WindMaster, without replacing the rest of the system.

FF Millbank Bag & Purification Tablets

A Millbank bag is a simple water pre-filter designed to remove mud, silt, sand, and other suspended particles from dirty water before boiling, chemical treatment, or further filtration. It is especially useful when collecting water from streams, rivers, or pools where the water may look cloudy or contain visible debris. It can also help improve the effectiveness and lifespan of water filters such as LifeStraw filters and Grayl bottles, and is useful when paired with water purification tablets.

The Forest Fundamentals Millbank Bag is based on the original British Forces design, but updated with a larger 12oz unbleached cotton canvas body, reinforced stitching, printed instructions, and a long survival cord lanyard for easier hanging in the field. It also comes with a waterproof carry pouch, making it easier to pack away after use without soaking the inside of your bag.

FF WindShield

If you've ever used a gas stove in windy conditions, you'll already know how beneficial a quality windshield can be. A good windshield can significantly reduce boil times in the wind while also improving fuel efficiency, helping you get more from each gas canister.

The FF Titanium Windshield is laser cut from sheet titanium, making it exceptionally lightweight. It is specifically designed to nest around the inside of a 750ml or 900ml cup/pot, allowing it to be stored neatly alongside the gas canister without taking up additional pack space.

Available in both 750ml and 900ml sizes, each windshield is designed specifically for this style of nested gas canister cook system.

FF Insulated Gas Canister Base Mat

The FF Insulated Gas Canister Base Mat is a simple but effective tool for insulating your gas canister from cold ground. Placing a canister directly onto cold ground for extended periods can draw heat away from the canister, reducing gas pressure and affecting stove performance, especially in colder conditions.

The mat creates a lightweight insulating barrier between the canister and the ground, helping the canister retain warmth and maintain more consistent performance while cooking.

110g / 230g Gas Canister

Depending on the trip length and how many people are using one gas canister, we will usually carry either a 110g or 230g canister.

As a rough guide, many hikers estimate around 5-10g of gas per 500ml boil, depending on the stove, wind, temperature, water volume, and whether you are using a lid or windshield.

For simple hiking meals, three boils per day may use roughly 15-30g of gas. Based on this, a 110g canister may be enough for around 3-6 days of solo use, while a 230g canister may be enough for around 7-14 days.

This is only a rough guide. Fuel consumption can vary significantly depending on the stove, weather conditions, altitude, and how often you are cooking. We still always overestimate our gas requirements, especially on longer trips or in colder conditions.

750ml / 900ml Titanium Pot or Cup

Both the 750ml and 900ml cup sizes offer a practical boiling capacity, requiring only 2-4 boils for a full day's water supply for one person.

They are also large enough for cooking and eating, but not too large to make drinking impossible, removing the need to carry separate bowls, plates, trays, or coffee cups. While they are not ideal for frying or more complex meals, in our experience they are the perfect size for MREs, rice, beans, and other simple hiking foods.

The 750ml size is also designed to nest with 32oz wide-mouth bottles, including popular options such as Nalgene, Pathfinder, and the stainless steel Stanley Adventure Series. They are also intended to work with the Forest Fundamentals Nesting Stoves.

Made from Grade 1 titanium, both sizes are extremely lightweight, highly heat resistant, and naturally corrosion resistant. True to titanium's nature, they are built to handle repeated outdoor use without cracking, rusting, or adding unnecessary weight to your pack.

Cleaning Bits

Often overlooked, a good cleaning kit is one of the best ways to keep cooking headache-free in the mountains. As a general rule, we always carry one wet cloth, one dry cloth, usually a cotton bandana, and a scouring pad. Burnt-on food at the bottom of your cup is sometimes hard to avoid when cooking over a gas stove, so a scouring pad is always useful.

It is also good practice to keep these items inside a waterproof zip-lock bag when out on the trail.

Cleaning aside, a good-quality cotton bandana is useful for preventing rattling inside your cook kit, wearing as a bandana, and can also be used as an improvised water pre-filter in a pinch.

Small Folding Gas Stove

Arguably the most important part of the kit: a solid folding gas stove.

For years, we used an unbranded stove from Amazon, just something inexpensive with good reviews. Despite its low cost, it never let us down, even in below-freezing conditions.

More recently, we've switched to the MSR PocketRocket Deluxe, mainly because of its built-in pressure regulator. This helps maintain more consistent performance as the canister empties and can be particularly useful if you're regularly cooking in sub-zero temperatures.

For most people, however, a simple unbranded stove with good reviews will do the job just fine.

Frequently Asked Questions

What size gas canisters nest inside which cup sizes?

The 750ml / 25oz pot is intended to nest with 100g / 110g gas canisters, roughly 3.5oz to 3.9oz.

The 900ml / 30oz pot is intended to nest with 220g to 230g gas canisters, roughly 7.8oz to 8.1oz. It can also be used with smaller 100g / 110g canisters if preferred.

I am only looking to buy one cup and bag size. Which one would you recommend?

We would recommend the 900ml bag and pot set-up. It provides more flexibility for different trip lengths, cooking styles, and carrying options, including carrying more gas for longer trips or for 1–2 people.

The 900ml set is slightly larger, but the difference is not very noticeable inside your pack. The overall set-up is actually slightly shorter, but wider, and the weight difference is also fairly minimal.

You also still have the option of carrying a smaller 100g / 110g gas canister inside the 900ml pot if you are hiking alone for a few days.

Do the windshields fit inside the bags?

Yes. Our windshields are designed in two separate sections, so they can be taken apart and packed inside the pot, around the edges of the nested gas canister.

What size windshield do I need?

Our windshields are designed specifically for 750ml and 900ml cup / pot sizes.

They are also designed to work with this gas stove set-up, using mini gas stoves that screw directly onto the canister. We do not recommend buying them for alcohol burners, Jetboil-style systems, or other stove types.

Do the FF gas stove bags fit non-FF cups and pots?

Yes. Our 750ml and 900ml pots use common, widely used sizing, so the bags should fit most similar-sized pots from other manufacturers.

On the off chance the bag does not fit, we provide free returns for all domestic customers here in the UK.

What size gas canister / cup do I need if I am only out for a few days at a time?

As a rough guide, many hikers estimate around 5–10g of gas per 500ml boil, depending on the stove, wind, temperature, water volume, and whether you are using a lid or windshield.

For simple hiking meals, three boils per day may use roughly 15–30g of gas. Based on this, a 110g canister may be enough for around 3–6 days of solo use, while a 230g canister may be enough for around 7–14 days.

This is only a rough guide. Fuel consumption can vary significantly depending on the stove, weather conditions, altitude, and how often you are cooking. We always recommend overestimating your gas requirements, especially on longer trips or in colder conditions.

Do the gas stove bags work with MOLLE, and do I need any attachments?

Yes. Our gas stove bags are designed to be MOLLE-compatible.

To attach them to the outside of your pack, you will need one of our MOLLE webbing strap sets. These straps are universal and will also work with other standard MOLLE pouches and gear.

What else would you recommend carrying inside the FF gas stove bags?

This depends on your trip style and personal preference, but at a minimum, the bags are designed to hold a titanium pot / cup, nested gas canister, and mini gas stove.

On our trips, we also pack the following inside the bags:

  • Lighter
  • Pot / cup lid
  • FF Titanium Windshield
  • Cleaning and drying cloth
  • Titanium spork
  • Water purification tablets
  • Tea, coffee and UHT milk sachets
  • Small gas canister stabiliser, sometimes
  • FF Millbank Bag
  • FF Insulating Gas Canister Mat
  • Campingaz CV gas canister adaptor

Aside from food, water, and a water filter such as a Grayl or LifeStraw, this set-up contains all of the cooking, drinking, and water-related kit we take into the mountains for multiple days at a time. The longest trip we have used this set-up for is six days.

Do the insulated gas canister mats fit inside the bags?

Yes. The insulated gas canister mats are designed to sit directly above the gas canister inside the bag.

They are also useful for reducing rattling and helping stop items from knocking together while you are on the move.

Do you sell the gas canisters and stoves?

No, unfortunately we do not sell gas canisters or gas stoves.

What is the Peak Limits Series?

The Peak Limits Series is focused on lightweight hiking, trail-running, and mountaineering kit.

Our first products are designed around the popular nested gas canister cook set-up, where a 110g or 230g gas canister, mini folding stove, and small accessories are stored inside a 750ml or 900ml cup / pot.

What is the additional zipped organiser pouch for?

The zipped organiser pouch adds extra storage for smaller items such as tea, coffee, UHT milk sachets, water purification tablets, cloths, lighters, and other cook kit essentials that do not fit inside the main gas stove bag.

What gas stoves do you recommend for this set-up?

Honestly, if you are not camping in zero or sub-zero conditions, one of the cheaper screw-on gas stoves from Amazon, provided it has decent reviews, will usually be more than sufficient.

We used a similar budget stove for years before upgrading to an MSR stove. Despite its low cost, it never let us down, even in below-freezing conditions.

More recently, we have switched to the MSR PocketRocket Deluxe, mainly because of its built-in pressure regulator. This helps maintain more consistent performance as the canister empties and can be particularly useful if you regularly cook in colder conditions.

One thing we would recommend carrying is a gas canister adaptor. If you are hiking abroad, you will often need to buy gas locally, and it is not always easy to find the correct threaded Lindal valve / EN417 gas canisters. A small adaptor can give you more options if the local canisters use a different fitting.
