What is an Internal Frame Backpack?

An internal frame backpack is a backpack that comes with a frame inside. It is typically used when hiking rugged trails or when you are planning to go off-trail. Backpacks with internal frames tend to hold the weight closer to the body and take away the weight from your upper back, which also explains why they have more stability.

The internal frame makes the bag capable of handling more weight and allows it to maintain its shape no matter how much gear is put inside. Its sleek and more compact design makes it ideal for hiking through bushy terrains and those that require sharp maneuvers.


Internal Frame Backpacks Vs External Frame Backpacks

External frame backpacks used to be the standard for hikers in the beginning. But in recent years, internal frame backpacks started to go on the rise for several reasons.

The main difference between internal and external frame backpacks, as the name suggests, is the location of the frame. This decision on the part of the manufacturers was brought about by consideration of the terrains and the stability provided by the pack.

Internal frame backpacks are sleeker, more form-fitting, and hugs closer to the body, making them the ideal choice when going through terrains that are particularly bushy or where you have to make sharp twists and maneuvers.  They are also great for hikers who need to pack a lot of gear because internal frame packs can hold up to as much as 20 lbs without compromising your stability. Plus, they are lighter and appropriate as carry-on luggage.

External frame backpacks, on the other hand, put the weight on your upper back and distribute the weight to your hips, giving you a more upright walking posture. They also have a better ventilation system, which is one of the main reasons why they are ideal for use in the summer. However, they also tend to be significantly heavier than internal frame packs.


Why do you need Internal Frame Backpacks?

Assessing your plans and the condition of the terrain you are hiking to is essential before you decide to buy an internal frame backpack.

Will you be walking through rough terrain or climbing and descending on paths with steep incline? Are you planning to bring heavy gear with you? Do you experience challenges with your stability?

If you answered yes to all, then you need an internal frame backpack.

Packs with built-in frames are ideal for outdoor enthusiasts who have concerns with maintaining their stability and walking posture, especially if you are planning to traverse rugged terrain. Internal frame backpacks are designed so they hug closer to your body, meaning the weight is not only concentrated on your upper back but in the entire body and hips as well.

You would also need an internal frame pack if you intend to bring a lot of heavy gear when you travel. The built-in frame makes it possible for you to not feel the weight of the bag on your shoulders as much while also keeping your gear cushioned from banging or accidental slips. Plus, the straps and belts ensure that the load inside the bag does not shift as you move.


What Things To Look For When Buying Internal Frame Backpacks

Buying internal frame backpacks for your next travel adventure is not as simple as checking its storage capacity and feeling if the shoulder straps and waist belts are fully padded. There are several other things that you need to consider before you finalize your purchase, not only to make the most of your money but also to ensure that you are not putting yourself at risk by using backpacks that fall below the standard.

These are just some of the things you need to look for when buying internal frame backpacks:

  • Weight capacity

Of course, the first thing you are probably going to check is the weight or storage capacity of the backpack. This should depend on the length of time you are planning to go on an adventure. Will you be going for a day hike? Then a 50-liter backpack might be too big for the trip. Are you planning for a 3-week backpacking trip? Then you might want to check out backpacks with a storage capacity of 90 liters.

  • Sizing and dimensions

You might be confused with the difference between sizing and weight capacity. The former is the actual size of the backpack and how proportional it can be with your torso, whereas the weight capacity is your bag’s storage limit.

When buying internal frame backpacks, you also have to check if it can be adjusted to fit your size, especially if you have a smaller frame. A lot of internal frame backpacks sold in stores come with sternum and shoulder straps that allow you to adjust the position of the backpack according to your torso’s size. This way, you can maintain proper walking posture and eliminate the risks of slipping off.

  • Pockets and compartments

The number of pockets and compartments are another important factor to some. You would like an internal frame backpack that has a roomy and easily accessible main compartment as well as several other smaller compartments to help keep your things organized.

Deep side pockets would be great if you tend to bring water bottles with you all the time, while hooks and sleeves are ideal for water bladders that you can attach to a hose outlet. You might also want a backpack that has a zip-up compartment at the bottom for the rainfly or something that can serve as storage space for your sleeping bag.

  • Material and ventilation

When it comes to the material used, you’d want something that is durable at the same time breathable. Proper airflow is one of the things that backpack manufacturers closely pay attention to. This is because it is very important to keep you feeling comfortable while carrying heavy loads on your back.

You will not go wrong with high-quality polyester and nylon because they are both lightweight and durable. Take time to check if the backpack has mesh panels as well. An internal frame backpack that comes with mesh panels in the torso area has better ventilation compared to those that do not have one.

  • Removable daypacks

You might also want to consider looking for a backpack that comes with a removable day pack or top lid, which is ideal if you have quick day trips in between your backpacking adventures. A removable day pack is also great when mountain climbing, especially if you can only bring a few items to the summit. Try to look for a top lid that can be easily removed from the backpack and has ample space for a day’s worth of items.

  • Attachment points

These additional features also provide an efficient way for you to lug around items that you wouldn’t normally keep inside the backpack. Look for products with holes on the sides where you can insert a pickaxe, rope, tent, flashlight, para-cord, or even your sleeping bag. You can also consider internal frame backpacks that come with Molle loops to hold your removable day kits and equipment.


Frequently Asked Questions

  • Is it necessary to have an internal frame in my backpack?

Internal frames are there for a reason. If you are planning a trip that will last for more than a couple of days or if you are anticipating more than 20 lbs of load, it is ideal to get a backpack that has an internal frame.

The internal frame makes it easier for you to carry around a heavy bag without putting too much pressure on your shoulders and upper back. It also helps in maintaining an upright posture and stabilizing you and your items each time you move. It’s great for even weight distribution and allows you to pack more gear for your trip.

  • How do I select the storage capacity of my internal frame backpack?

The storage capacity of your internal frame backpack should depend on the length of your trip. Weekend trips call for weekend packs that can store anywhere between 30 and 50 liters. Multi-day adventures, meanwhile, require backpacks that have the capacity to hold 50 to 80 liters. Extended trips that may last for more than 5 days would benefit from internal frame backpacks with a 70 to 90-liter capacity.

  • Is it okay to not have a rainfly?

Rainfly is not a requirement per se, but it is very essential in keeping your belongings dry and protected A lot of brands manufacturing internal frame backpacks now include a rainfly in each of their products, so it should not be very difficult for you to find one.

But while there is nothing wrong with not having a rainfly, you would surely find it more advantageous if your items are weatherproofed. This is especially the case when you are traveling during the monsoon season. Aside from keeping your belongings dry, a rainfly also prevents the pockets and compartments of your backpack from being too exposed.


Internal frame backpacks are very trendy these days but there are still a lot of factors that you need to consider before making a purchase. You need to take time to examine your needs and preferences to determine whether you truly need an internal frame backpack or if your trusty external frame pack would suffice.

Among the first things you need to consider is the material of the pack and its customizability. It is also important to know if it’s suitable for your activities and if it can accommodate the amount of gear you are planning to bring with you.
