We use backpacks almost everyday  to transport items more easily, but do we know which bag to choose for a beautiful holiday hiking trip? The comparison we want to take a look at and see thecontrastis for internal VS external frame backpack. Each of these bags has advantages and disadvantages which will allow you to choose the backpack that fits you the best.

External frame backpacks

Positive features

Considered an “old school” backpack, the external frame backpack features, as its name calls it, an external frame which was designed to help people carry more weight and also to help them keep a straight posture while hiking.

In addition, the external frame backpack has unique characteristics, such as simplicity in coordinating your gear thanks to its large number of compartments  and the ability to have more small packs attached to its frame.

Moreover, the rucksack’s structure provides its user with a ventilated space between the user’s back and the bag’s external frame, allowing the person who uses it to feel more comfortable in hot weather situations.


Although the backpack can be used to carry heavy loads, its size is also one of the biggest drawbacks of this kind of backpack. Because of its bulk composition, the pack tends to lose its stability and it’s less balanced compared to the other types of backpacks.

Furthermore, the bag’s aspect is not helpful at all when hiking in dense vegetation areas nor when traveling by vehicles. Due to its square-shaped appearance, the risk of getting caught in branches is pretty high so it’s recommended you use this type for wide areas and well-known hiking trails, and because of its bulkiness, it might get damaged when carried by various vehicles.

Finally, the shoulder straps on external frame packs are harder to adjust, narrowing the range of heights for the people who want to buy one.

What more should I know about this type of backpack?

Compared to a frameless backpack, the external frame one offers the user better weight distribution and protection due to the fact that the frame is made mostly of aluminum, which is equipped with tight netting to prevent the frame making contact with the wearer’s back.

The price range for a good external frame pack is around  $150-$250 USD, which is a lot cheaper than an internal frame pack and also it is highly recommended that the back of the bag is made from waterproof material in order to protect your belongings in case of storms.

Moreover, pockets are also important for this type of bag. Depending on the length of the trip, choosing the number of pockets determines how much gear you can take with you. If it’s a short trip, a small number of pockets will make it easier for you to organize your gear, but if it’s a longer trip you need as many pockets as possible, especially elastic side pockets which will simplify access to the items you are going to use the most often on your trip.

Naturally, you have to pay attention in choosing the right capacity of your internal storage too, because this is very important for a hiker’s survivability.Same as choosing the number of pockets, choosing the capacity of the internal storage is also based on the length of the trip.

The storage is measured in liters and starting with a one-day trip, the recommended capacity is between 20-50 liters, for a weekend trip between 50-60 liters and for 5 or more nights, over 80 liters.

All of them have features like top loading, adjustable suspension, mesh water bottle pockets and padded shoulder straps in common, but what makes them unique are the few elements whichmakes a bag being the perfect choice for you.

For example, if you go on a hunting trip, you might want to choose a bag such as the ALPS backpack which has a rifle holder and a top loading fit for big game, or if you are afraid that the rucksack will get damaged after its first use, you can choose one of the Kelty backpacks available on the market, which include limited lifetime manufacturer’s warranty. So, to sum this up, the choice is held in place by the limits of your needs.

Internal frame backpacks

Positive features

In the last decade, that kind of bags became the most popular amongst hikers due to their internal, strategically built frames and their ability to integrate on one user’s back.

As they form onto your body, and “become a part of you”, the internal frame rucksacks offer extreme mobility and balance, making it easy to take tighter turns on narrow hiking paths, also making climbing steep hills or traveling mountain paths feel like a piece of cake.

In addition, compared to the external frame pack bags, the internal frame bags have a compact structure, making it easy to transport them by car or by plane, and also, the shoulder straps, in this case, are easy to adjust, so you don’t have to worry if another family member wants to use the bag.

Furthermore, these backpacks offer a large internal capacity that allows you  to store most of your gear inside to prevent accidents like snagging onto trees or bushes, and because most of them are made from waterproof material, your equipment is perfectly safe inside.


Despite their large internal storage capacity, the internal frame rucksacks tend to be messy when it comes to organizing your gear. Having only one large compartment inside, coordinating your equipment along the trip might prove quite difficult.

For example, imagine you need your flashlight, and when you search for it,remember that you packed it first so it is at the bottom of the bag, then you have to dig through all of your belongings to find it.Imagine doing this at night.

Moreover, the bags become uncomfortable when carrying heavy loads for longer periods of time, and unlike the external frame backpacks, the weight shifts to the lower part of the bag, forcing you to lean forward transferring the weight to your lower body.

Additionally, as the rucksack is made to be “glued” to your back, there is no ventilation between them, this making the bag feel very uncomfortable when hiking on hot temperatures.

Lastly, attaching external gear to these backpacks proves to be very challenging, as you must make sure the extra equipment is safely strapped to the bag and also if it still provides you quick access to your internal storage at the same time. Be careful. For more choices, check out our piece on the best internal frame backpacks to suit your needs.

Is this backpack for you?

Being the most used type of hiking rucksacks nowadays, we must ask ourselves, why do people choose this bag? The answer stays in its mobility, aspect, and feel. The internal frame bags look “sexier” than the external ones, due to their compact form and modern look, so it’s pretty obvious why they are so appealing to us.

On the contrary, a professional hiker never chooses his backpack only by its look, it must be good quality too, being the most important tool in a traveler’s survivability, so naturally, internal frame bags are much more expensive with a price range of above $200 USD.


The backpack’s internal frame is also made from aluminum, plastic or titanium, and it’s covered in large fabric, so we can pretty much say it has a brilliant structure. Also, the frame is sustained in place by complex series of straps, so the weight shifts less than the bulky external frame bags.

Over the years, the evolution of the internal frame pack bags can be easily noticed, as a result of their improved storage capacity and  comfortableness when casually walking, and in consequence, they replaced the external frame bags in different many activities.

The external frame backpacks are good for hiking trails, while the internal frame backpacks are the best suited for rugged, uneven terrain. Even so, the external frame pack bags don’t need to be left out, as you cannot find another type of bag which offers the same carry capacity as this one, and in addition, they are way more comfortable because of their ability to shift weight properly.
