Internal vs External Frame Backpack: Protecting Your Gear
Backpacking checklists need to be very comprehensive to ensure that you have packed everything you might need while on the trail. You need food, water, utensils, perhaps a stove and several other things, if you want to have a comfortable trip. However, the most important thing while out hiking is the backpack itself.
You need something which is strong, roomy, comfortable to wear and also lightweight. These are not the only considerations, though. Regular backpackers will know that there are two main types of backpacks – internal and external frame ones.
Both have their own merits and demerits. Here we will talk about internal vs external frame backpack, and discuss how they both differ.
Backpack Requirements and Things to Keep in Mind
There is nothing particularly wrong with any one type of backpack; they both just have different properties and uses. Therefore, when you are heading out for your backpacking trip, consider what your exact requirements are and then choose a backpack accordingly. Do your research – you do not want to go on your trail while carrying the wrong backpack.
Let’s talk, first, about what general points you need to keep in mind when purchasing a backpack.
- Capacity and Weight: How many things do you need to carry? Are you just going for a day-to-night trip or will you be spending several days on the trail? You need more stuff if you will be hiking for many days, and thus need to choose a backpack with sufficient storage capacity. Most backpacks have their capacity mentioned in cubic centimeters or inches. Comfort: Your backpack needs to rest comfortably on your back, with the shoulder and waist straps adjusted properly. Both internal and external frame backpacks have their own pros and cons in terms of comfort, and we will discuss them shortly. Mobility: Are you going on a straight, even path or will you be hiking in the wild, with rough terrain and climbs and falls? This is a very important question to consider before choosing your backpack. Compactness: Backpack compactness is another important consideration. Do you want a compact backpack which can easily fit inside the trunk of a car? Consider the overall size and weight of the backpack, too, before buying it.
What are Internal and External Frame Backpacks?
First, let’s understand the difference between the two types of backpacks, and then we can discuss their pros and cons.
- Internal Frame Backpacks:The suspension system is present inside the bag, and mostly in the form of aluminium stays. These backpacks have a lot of capacity inside, and are quite roomy. External Frame Backpacks: As the name suggests, these types of backpacks have a suspension system made of a rigid frame which is present outside the bag. The frame is mostly constructed out of aluminium.
Properties of Internal Frame Backpacks
Internal frame backpacks have their own set of specific properties, which make them different from external frame ones:
- Position: An internal frame backpack lies close to the back. As a result, it does not shift your center of gravity very much. These bags lie snug against the back and move around very little when you move. The straps on these bags can be adjusted to suit your comfort. They can be tightened and loosened, to ensure that the backpack rests properly against your back. Shoulder straps can be adjusted so people of all heights can wear the backpack with ease. Capacity: These packs have a lot of internal space. You can pack all of your stuff inside. Most of these bags allow access from the top, although some new ones do have front access, which makes it easier to pack your stuff. There is usually one big main compartment, with a few small side pockets. Most of the things are meant to be carried in the main compartment. Mobility: Internal frame backpacks allow a greater deal of mobility than external frame ones. Because the backpack lies next to your back, it does not hamper your motion or bump across your back when you make rapid movements.
Advantages
Here’s what you get when you have internal frame backpacks.
- You can Move around very easily while you are wearing this kind of backpack. This means that you should definitely go for an internal frame backpack if you will be traveling on a rough terrain with many up and down trails. If, for example, you plan to hike in rocky or mountainous terrain, you should go for this type of backpack. The backpack Lets you store a lot of stuff inside, which works well if you are hiking in a region where there are bushes or branches which may snag your stuff if it is held outside. These bags are Compact in size. This means that if you plan to reach your destination by car, you can easily fit this backpack in the trunk. It can even fit in the overhead compartment of an airplane. The support system of an internal frame backpack is mostly made of Aluminium rods, which can be bent and shaped according to your preference. This means that if the bag feels uncomfortable across your back, you can bend the aluminium stays to match the curvature of your back, and hence feel more comfortable. They are Ideal for tight and small trails where you need to maneuver with care.
Disadvantages
Just like with pretty much everything in life, internal frame backpacks come with their own set of disadvantages:
- As mentioned before, internal frame backpacks Lie very close to the back. As a result, they allow very little air to pass between your back and the pack, and hence they can make you feel quite hot. If you are backpacking in warm weather, it is very likely that you will sweat a lot. This means that you might get uncomfortable and may even have to stop to cool down. Some new internal frame backpacks come with ventilation channels, or nylon mesh at the back, which is meant to wick sweat away and make you feel cool and relaxed. If you are used to hanging things from your backpack, this backpack design is not the best one for you. It does not have many places for you to hang stuff from, and so you have to carry everything inside the bag. This might be a problem if you want to carry things which cannot be packed inside the backpack, like a rifle, or a large tent. The backpack rests in such a way that Weight is carried lower on the back, which means that you have to bend forward a little to feel properly balanced and comfortable. Therefore, for straight trails, this may not be the perfect option. Usually, backpacks of this style have only a Single big compartment, which means that if you need something that you have packed at the bottom of the pack, it can be quite a hassle to take it out. Some backpacks do come with small side pockets, but the main compartment is single and only has access from the top. Therefore, you have to pack very carefully. Thus, this type of backpack should not be your ideal choice if you may need to pack and unpack your things very often on your trip. They are Not ideal for carrying very heavy and bulky objects, like sleeping bags. They are Pricier than external frame backpacks.
Check out our piece on the top internal frame backpack to give you more choices.
Properties of External Frame Backpacks
Now let’s discuss the specific properties of external frame backpacks, which may be better suited to your needs:
- Frame: These backpacks have a rigid aluminium frame, which cannot be bent. Weight Transfer: These backpacks are designed in such a way that they transfer weight to your upper back. This lets you walk straight, with a proper upright posture. The pack is held slightly away from the back and does not hug it. Weight: They are heavier than internal frame backpacks. Compartments: These backpacks normally have more than one compartment. There are many zippered pockets for storing different stuff. Attachment Points: External frame backpacks have several attachment points from which you can hang different objects.
You can attach sleeping bags, bear canisters and even tents with these attachment points.
This means that these bags let you carry a large amount of weight; and a lot of stuff which cannot fit inside the bag can be hung from it outside.
Advantages
External frame backpacks have the following advantages:
- You can carry your tent and sleeping bag with this backpack. This means that if you plan to go for longer hikes and need to carry a lot of stuff, you should get this backpack. It Divides the weight evenly and hence lets you walk straight. You do not have to bend forward to feel like the weight is properly distributed. These backpacks are Not hugging your back, which means that they allow air to pass between the pack and your back. As a result, you will not sweat quite so much and thus these bags are a good idea for hiking in hot weather. The backpacks have A lot of compartments, which makes it easy to store different types of stuff and keep your things organized. Packing the backpack is thus easier, and so is unpacking it.
Disadvantages
On the flip side, this type of backpack frame too, have its disadvantages.
- These kinds of backpacks will Move and bump across your back if you move about too much. As a result, they are not ideal for uneven terrain where you may need to climb or jump. They are Bulky and thus can be cumbersome to carry. If you plan to travel by car, or by plane, it can be difficult to fit the backpack in the designated space. These bags Do not feel very stable and you run the risk of falling down if you do not walk upright, or make a hasty jump. In the wild, where there are a lot of branches, the stuff you are hanging off the Bag might get snagged and stuck. The backpack itself is difficult to maneuver through tight spaces and small trails. External frame backpacks are Heavier and thus more difficult to carry than internal frame ones.

Which to Use
Now that we have discussed the properties and pros and cons of both types of backpacks, let’s get down to the important question – which backpack should you use and why?
There is no simple answer to this question. Which type of backpack you end up using depends entirely on your needs, the amount of stuff you are carrying, the type of trail you will be hiking on, how many days you will be hiking and of course, your own preference. That being said, it is also important to note that internal frame backpacks are all the rage these days, with most backpackers opting for this option.
If you need to decide which type of backpack to carry, consider this brief suggestion. If you plan to hike in definite, marked ground where the trail is straight and even and there will be no jutting branches, you can consider using an external frame backpack.
You should also go for this type of backpack if you want to carry a lot of heavy stuff which will be difficult to carry inside the pack, and may need to pack and unpack things quite often.
However, if you want to go hiking somewhere where you will have to move about a lot and may need to climb and jump, you should go for an internal frame backpack as it lets you move more easily. This type of backpack is also ideal for the wild, where you may need to maneuver through tight spaces and thus need a more compact backpack.
The Right Backpack can Make all the Difference
If you go on a hiking trip and your backpack is not comfortable or does not suit your needs, your whole trip will be ruined. Therefore, before setting out on the trail, always consider your needs and requirements and choose a backpack accordingly.
If you are a regular hiker who goes on hiking trips quite often, it won’t hurt to purchase both types of backpacks and use them as and when required. After all, having a perfect backpack is essential for a great hiking trip, so you should definitely invest in a good one.

Internal Frame Hiking Backpack
A lot of people seem to be asking why the shift from external supports on knapsacks to internal ones. I have to admit, I started to wonder the same thing. Was it because customers were losing interest in the external frame or was there another underlying reason?
It turned out to be an odd conundrum, simply because hard core users wanted more selection in externals whereas manufacturers were moving toward producing a larger variety of internals. As my brother and I researched a little bit more we found out why the popular trend to an internal frame hiking backpack.
Apparently, there are several reasons for the newer internal supports, but they all come down to one main trait and that is stability. Let’s take a look at how these models can be better for you than the external ones.
First, when the metal or aluminum supports are on the outside of the bag, they can get caught on things which can be irritating and at times downright dangerous. If you are traversing thick brush, for example, you don’t want anything hanging out that can be grabbed by tree branches, thorns on twigs, or prickly bushes.
As you walk, you have a certain momentum, and if that is broken, you lose stride and possibly your balance. Once you become wobbly, it is so easy to fall. Plus, when something heavy like your bag is caught, it can do damage to your body as it pulls you back. All of this comes back to the issue of stability.
Second, the flat bars that make up the inside support are often shaped according to a person’s back. To keep the load where it belongs, making it the most comfortable, as well as healthier or safer for various body parts, the supports should be made to transfer the load to the hips.
Third, the pack sits flush against your back making the body and sack one. With the proper adjustment of shoulder and waist straps, this should result in little movement of the pack, which is advantageous and safer when trying to get up tight hills, and when crevices can cause tripping. Rock climbers are particularly happy with this style.
Fourth, these models tend to be better than the old one size fits all. Again because the straps can be tightened and loosened, more precise sizing is possible. This is an obvious advantage for both short and tall persons. If your pack fits you better, then it is more comfortable and you can enjoy your hike instead of complaining about the load.
Fifth, the stays or flat bars that make up the support can be bent by hand giving the wearer control over the tightness and feeling of support. And if you are walking and the fit doesn’t seem quite right, you can mold the back stays on the fly to make things more comfortable and natural for you.
Sixth, although this has nothing to do with safety or stability, this type of knapsack folds up smaller and is less cumbersome for storing than its counterpart.
Conclusion
We had a lengthy discussion with our walking group and it seems that although everyone has their own preference, most of the participants have gone to the internal frame hiking backpack. Our buddy Jack said that his was more expensive to buy, but he really felt the difference when he used it a couple times.
He mentioned that his back wasn’t as sore that night. He also liked the fact of not being able to connect a bunch of stuff to the outside. In the past, he just took way too much junk he didn’t need and since this newer type frame discourages that sort of behavior, he was a lot happier.

What to Look for in a Good Internal Frame Backpack?
Choosing the right internal framed backpack is a very important element to any successful trip. If you choose a pack which is too heavy, you will be in for a long haul and a very sore back, and if you choose a pack which is too light you may not be able to get all of the necessary gear or clothing in your pack and be left stranded in the rain without the proper attire. With so many options available on the market today, it can be extremely confusing as to which internal framed backpack is the right one for your needs. Some of the most important things to consider when shopping for a good internal frame backpack are:
- Water resistant material – even if the backpack is not 100% waterproof, it is extremely important the material be at least semi-water proof to help protect the contents of the bag from sprinkling rain. A semi-water proof material will allow you to keep hiking and give you adequate time to get out of the rain, all while protecting the contents of the backpack.
- Lockable Zippers – lockable zippers are a feature which often gets over looked, but can come in extremely handy. Not only does it keep people out of your packs if you are traveling via train, bus, or airplane, but is also keeps animals like raccoons out, when you are out in the wilderness. It is also really comforting to you know your belongings are locked in safely in case you trip and fall and drop your pack and give you piece of mind that your belongings won’t be tumbling down a hill, or into a lake, if your pack is dropped.
- Padded hip belt – since most of the packs weight will be supported by your hips, it is vitally important to ensure your hip belts is padded. Not only does the hip belt provide support, but it also aids in distributing the weight of the pack across your back, shoulders and hips to help eliminate pain and stress.
- Padded shoulder straps – like the padded hip belt, padded shoulder straps will make carrying the backpack a lot more comfortable. Padded shoulder straps also provide a space between your back and the pack, allowing for airflow and to help keep you cooler.
Choosing the Right Capacity – why does it matter?
Ensuring you have the right storage capacity with your internal framed backpack is extremely important. The right capacity equates to having the right storage and internal volume available inside the pack. The internal storage capacity is measured in liters, so it is easier to compare one pack with another and also extremely easy to remember.
When considering what the right internal capacity is for you, you need to first consider what your needs are. Are you going on a long trip or a short trip? Do you hike or camp often? How much weight do you want to carry?
Below is a list which can be is used to help find the right internal storage capacity based upon their needs.
- Day/Overnight trip = 20-50 liter pack capacity Weekend (2 to 3 nights) 50-60 liter pack capacity Multiday trip (2 to 5 nights) 60-80 liter pack capacity Extended trip (5 or more nights) 80 or more liter pack capacity
If you go on both long and short trips, it is recommended to purchase two different packs. A lighter model pack will be more than sufficient for shorter trips, while a longer trip will require more gear, and therefore a larger pack.
Fit Customization Tips
The most important thing to consider when finding an internal backpack which fits is to consider the length of your torso. Regardless of how much gear you have, or how light your pack is, if the frame does not fit your torso well, it is going to be a long uncomfortable hiking experience. A properly fitting frame is one which will grip snuggly to your hips and is also size appropriate to your torso length.
Another excellent customization feature on a lot of internal framed backpacks is adjustable suspensions. Adjustable suspension systems allow the shoulder harness, or straps, to be adjusted to provide a more body specific fit. This is a great feature for people who are in-between heights and sizes, such as a teenage boy.
Packing tips
When deciding how to pack your gear there is actually a few key items which need to be taken into consideration.
Main compartment – this is the perfect place to pack items which are not needed right away, such as a sleeping back or a change of clothing.
Outside pockets – perfect for holding water bottles, snacks, a map, pocket shovel, or other small items which may be needed often.
Top lid – this is the perfect place to keep a camera, snacks, a map, sunscreen or other items which you plan to use a lot.
Typical cost of an internal frame pack
Much like there external frame counterparts, internal frame backpacks can range drastically in prices. Smaller, less durable packs can cost as little as $49 USD, a middle of the road pack will cost approximately $110-$150 USD while a top of the line pack will run a person anywhere from $169 – $269 USD.
