Comparison review: Comparing lightweight backpacks perfect for light mountain hiking and fast packing

Hiking, climbing, fast packing, trail running. With the diversification of outdoor activities, the types of backpacks have become more diverse and complex every year. Conversely, even if it is the same size, we are in a time when you can choose the perfect item for you, which is more comfortable from a variety of backpacks depending on the season, purpose, and way of thinking. explains the topics on this topic as " How to Choose a Mountaineering Backpack

This time, we focused on the genre of "lightweight backpacks," where interesting models from various manufacturers are beginning to appear this season from among these different types of backpacks. We have picked out 10 items, from the latest models to existing popular models, and compared them under the same conditions, and compared them from various perspectives. We will introduce the "vest/lightweight backpack" that is perfect for light hiking, as well as other recommendations based on your preferences.

About the backpacks compared this time

When it comes to mountain climbing backpacks, the typical type is ones made of durable fabric (a backpack for traversing) with a sturdy frame built into them so that they can withstand large loads of around 20 kg. However, if you are planning to go out quickly over a familiar mountain area with lightweight tools over the weekend, the recent backpack situation is that lightweight backpacks that pursue a balanced balance of lightness and ease of use are more convenient to use. Of course, it is also good for fast packing, where you can run through longer distances based on solid preparation with lightweight equipment. When selecting this category, we assumed the purpose of these, and first narrowed down our backpacks roughly using the following criteria:

• Capacity is 30-40L
• Models available for purchase in Japan
• Pack weight is less than 1kg
• Models with minimum back pads (excluding models with none at all)
• Models that are basically intended for hiking and trekking (excluding models exclusive to trail running and climbing and skiing)

From there, we finally picked out 10 items, including design, price, and personal preferences. To be honest, there is a huge variety, from models that are easy to obtain at mountaineering mass retailers across the country, such as the North Face and Montbell, to garage manufacturer products that can only be ordered individually via semi-order online, to the latest models and popular models. Put another way, models famous for activities called "ultra light hiking" coexist on the boundary line with models from brands that people familiar with ordinary mountain climbing would prefer.

The site's stance on this is not to be caught up in strange labeling or preconceived notions when you haven't actually tried it, but to settle the objective conditions as much as possible, open up the information, and simply discover "good things" and share the information. As a result, the comparison may not work, but at that time, I would just admit my failure and move on to the next step as a source of energy for the future, and this time I think I made a meaningful discovery in my own way, so I have published this comparison. Well, you won't know anything unless you try it and look at it, so I hope you will be able to stay with us with a broad mind.

The story has been a bit off. In addition, there are considerable differences between products in terms of "availability" and "price," but in this comparison, we ignored them from the perspective of a pure comparison of quality. An overview of the 8 of the 10 items we have picked (excluding HMG, mountains and roads) is introduced in 10 Recommended Lightweight Backpacks

Test environment

The test period for the lightweight backpack is approximately six months from April to September 2016. The test is only done by the author. All items are purchased by themselves. I tried on the mountains near Tokyo and in Okuchichibu and Joshinetsu (around 1,000-2,000m). In addition to taking one pack normally on hiking all day, we also carry out tests when conditions are met, such as carrying all the packs on the same route and weight on the same day (as expected, we have not been strictly meeting the conditions such as time of day, weather, and fatigue). During the test, the overall weight of the pack was approximately 3kg, which is intended for day trip equipment, and approximately 7kg, which is intended for staying in a hut or in a tent at Ultra Light (UL), and we also tried it out when the pack was 14kg as a reference value, making it comfortable to carry. Other detailed test conditions are supplemented in a detailed review of each item.

Regarding evaluation items

First, the essential lightness is compared by "weight per unit capacity" and evaluated as unit weight. Regarding comfort, we evaluate comfort, including the load when walking with heavy load, as comfort, and mobility when walking quickly or running with light luggage. In addition, we have evaluated the ease of packing and expandability of various pockets and attachments, as well as the functionality of the user-friendliness and all of the unique features, such as ease of packing and expanding, ease of installation of hydration, luggage storage, and whether or not there is a mat on the back and rain cover.

Note that the evaluation values ​​for the test results are merely relative indicators within the test, based on the judgment of the evaluator who conducted the test and do not have any objectivity.

Mountains and Roads ULFramePack ONE

When it comes to mountains and roads, it is a garage maker that is known only to a few people in Japan's UL community. ULFramePack ONE is its flagship, ranks number one overall, despite famous brands around the world. After comparing various cases this time, the overall high quality, which is not just within the "ultra light" frame, has greatly disappointed my prediction in a good way.

First of all, the body weight is around 600g*, the lightest of this time, and it is also large enough to pack in a 40 liters or so. I think this alone is a surprise, but in a sense, it may be natural lightness for this model, which is made with the UL backpacks that are mainly used in the battlefield at around 500g. And here's where the amazing stuff about this pack starts. The selling point was not simply light.

What surprised me most was the back structure, which is so comfortable that it would be impossible for such a lightweight backpack. The X-shaped carbon frame pulls the stabilizers on the shoulders and waist to moderately flex and fits the line of the back to ensure a secure fit. The load firmly reaches your back and waist, making it comfortable, not just for UL. Even if you carry as much weight as you can, there is almost no strain on your shoulders, allowing you to move comfortably for long periods of time. Moreover, the balance of the shoulders, back and waist can be freely adjusted depending on the pull of the stabilizer, so you can fit according to your preference, such as mainly shoulder weight when the luggage is light, and mainly waist weight when the luggage is heavy.

The exterior has a waterproof zippered pocket, a front pocket for large items, a side pocket that can be cut diagonally and makes it easy to take out bottles while carrying it on your back, and a versatile drawcord, and each one is carefully crafted with ease of use for users.

The problem is that (although this is not included in this review), they are basically only accepted online custom orders, and are priced not cheap, and the high hurdles are that they can only be purchased with a delivery time of several months. However, on the other hand, the customizability and premium feel, which allows you to choose the size, fabric and coloring yourself to a certain extent is an irreplaceable appeal, and I was able to fully feel that this quality is a quality that you will never regret even after paying this much. It's a nod to the point that it's still popular, even after a few years since its release.

*This is the subject of the fabric and size selected by the author (main fabric: 70D Silicone Coated Ripstop Nylon, external pocket fabric: X-Pac VX07, back length 51cm). Please note that the weight and other details may vary depending on the order.

Recommended for its comfortable carrying comfort and ease of use

THE NORTH FACE Kyle's 35

If you want a lightweight backpack to be the same comfort when carrying it on your back, to packing and use when taking action, and what you're looking for in a lightweight backpack that's just the same, just like the traverse backpack you're currently using, there's no other option.

The trampoline-structured rear frame is a feature that has become a huge hit in basic mountaineering backpacks these days. The fact that it is used in a lightweight backpack weighing around 1kg is the biggest selling point of this pack, with a flexible back panel that fits tightly and the airflow that passes through the back ensures a comfortable carrying experience even in the middle of summer. Furthermore, the relatively sturdy aluminum frame and large hip belt seem to be weighed almost on the waist even if it weighs over 10kg, so its high stability is a major advantage that other models do not have. However, it seems that it is a bit difficult to say that it is perfect for trail running.

It's easy to take out pockets and attachments on the front and sides, a zipper opening and closing that allows you to access the main compartment without opening the canopy, and an included rain cover, so you won't have to miss its high storage and functionality. Apart from being lightweight, it is a magnificently "normal, easy-to-use backpack", which means that it is a terrifyingly well-made model.

In addition, we previously introduced the details of THE NORTH FACE Kyles 35 on this page .

MILLET Venom 30

If the TNF is an easy-to-use model similar to a normal traverse backpack, this model is easier to use for speed hiking and is similar to a regular backpack.

The 30L capacity is about 900g, but of course it doesn't feel particularly heavy when carrying it on your back. The slim, compact body and excellent breathability and fit, the back, shoulder and hip belt provide comfortable carrying comfort and ease of movement within a range that does not exceed 8kg. The front and side pockets allow you to take out bottles and other items while standing, as well as an optic opening mechanism that allows you to quickly open and close the canopy from the back, and a speed pole loop that allows you to attach the pole without lowering the pack while you are still in motion, making it a clever way to say that it's a no-miss feature that's not a hit. Finally, it is worth noting that the fabric used for the body is firmer than other packs, making it a very durable one, as Millet, who has produced many alpine-style backpacks.

In addition, we previously introduced the MILLET Venom 30 in detail on this page .

No.1 in cost performance

mont-bell versalite pack 30

Considering the price and availability, the mont-bell versalite packs are on the right. In an age where it can even be presumptuous to ask for so much from a backpack priced below 10,000 yen, the overwhelming cost performance of this pack was impressive.

In this comparison, the team ranked third in terms of its essential weight per capacity (unit weight), third in terms of mobility evaluation, which is the comfort of working with lightweight equipment, and second in terms of functional evaluation, which evaluates detailed usability. In short, I felt that its performance would be top-class if it was intended to be used in light and fast (a total weight of less than 5kg). It's available at an extremely affordable price, so in that sense it's well worth considering.

However, be careful not to use anything other than the above, so if you make a mistake, it will be quite a shame. The fabric is fluffy and doesn't really feel comfortable in terms of durability, and the fact that it is a type of fabric carried on the shoulder and the back panel with only pads makes it too much of a strain on the shoulder if it weighs over 7kg, and the pockets are not easy to use, so it is honestly undeniable that it is quite comparable to other excellent models. It is by no means a main pack, but it is a model that has a strong presence when you decide on the purpose and consider it to be a consumable item.

Recommended for long distance courses that mainly run trails

ULTIMATE DIRECTION Fastpack 30

If one pole is used as a lightweight backpack to walk lightly and comfortably, the other pole is to move quickly with minimal load, that is, trail running. Of course, there are a lot of packs specializing in trail running available, but most of them have a small capacity of around 10 liters to suit short courses such as races. the ULTIMATE DIRECTION Fastpack 30, which combines high storage capacity that allows you to stay in a tent and a structure optimized for running, is quite valuable, and even in tests, I was able to get the best feeling when running on the course with light luggage.

Needless to say, its major feature is its vest-shaped shoulder harness. Unlike a typical backpack, the style is clamped by two adjustable sternum straps and underarm side straps to provide a high fit without a hip belt. The large shoulder strap not only distributes pressure and maintains comfort even when tightly tightens, but also allows you to store water bottles, gels, mobile devices, etc. The freedom of the lower body and convenience in the front thus obtained are very convenient for speedy actions, providing a comfortable running environment that is unlike any other model. The highly elastic pockets on the front and sides are also very convenient.

On the other hand, it's a bit disappointing that the burden of over 5kg and the performance was worse than expected when he acted full capacity. The load on the shoulder increases the uncomfortableness, and the pack shakes greatly when riding, making it difficult to say that although it is not very easy to drive. Furthermore, the durability of the fabric and straps was used, and the damage was immediately apparent, leaving me worried about the durability. Therefore, it may be best to remember that other ultralight backpacks may be more effective when running trails over multiple days, if you are not confident in reducing the packing size, or if you are not particular about the best type as a preference, you may want to remember that other ultralight backpacks may be more effective.

Detailed reviews of each item

Unit weight

The candidates we have picked this time are not necessarily just models that are light, but since it's a lightweight backpack, it's only natural that it's a good idea to buy one that's as heavy as possible. That being said, simply comparing weights does not reflect different sizes (capacity) for each model, so it is necessary to give a proper and fair evaluation. Therefore, in this comparison, we first remeasured the actual capacity and weight of each model to ensure greater accuracy.

Since each manufacturer follows their own method of measuring the normal capacity, it is not possible to compare strictly relative to each official information. So this time, we will re-measured all models using the indicator, "How many ping-pong balls can fit." The diameter of the ping-pong ball is approximately 40mm (0.4cm), so we have converted it to liters, assuming that it occupies 0.064 liters per piece. The pack is of course flexible and the individual ping pong balls are slightly distorted, so this value does not indicate a strict volume. Please note that this is only a guideline for the relative comparisons this time.

In this way, per unit capacity (1L) of the backpack is calculated from the total volume combined with the main storage area and the rest (canopy and other external pockets) all accessories installed The results are summarized below:

*1 This is based on our own measurement results, which converts the number of ping-pong balls (40mm diameter) into liters, so this is just a guideline for this comparison.
*2 These are actual figures that include all removable parts and accessories (rain covers, etc.).
*3 Main body fabric: 70D Silicone Coated Ripstop Nylon, external pocket fabric: X-Pac VX07, back length 51cm

From here, the first thing you can say the mountains and roads. ULFramePack ONE 's overwhelming lightness. Not only is it the lightest, but it also has a large storage capacity thanks to its main storage that can be packed to the very least and a large external pocket. Plus, the small capacity allows you to tighten the compression on the sides to maintain balance, and even with a large capacity, the frame is firmly inside, so the pack does not lose its shape, making it a great performance that is not just about specs. Similarly, the Gossamer Gear Gorilla 40 (although it's heavier than the previous model) had a very good balance of lightness and capacity.

Meanwhile, the Mont-bell Versalite Pack 30 and Montane Ultra Tour 40 also have top unit weight scores. However, as far as I have used these two things, you should be careful about: the back pads are poor, so if you fill them up as much as you can, the pads will become distorted or too heavy to hurt your shoulders. It may be better to assume that it is not packed with much capacity that is essentially "usable" in size.

The MILLET Venom 30 , THE NORTH FACE Kyles 35 , and THULE Stir 35L but I would like to add that these were a trade-off for the comfort of carrying, which will be explained later.

Comfort

Lightweight backpacks are naturally not suitable for the comfort and stability of a traverse backpack with strong support and thick cushions for traversing. However, this does not mean that you should give up on the comfort of carrying it or the lack of fatigue from long-term movements.In this category, we compare how the load of around 3 to 10 kg, which is expected in this category, provides a comfortable carrying experience. The two points we evaluated in this comparison were the comfort of carrying the body, such as the back, shoulder and hip belt, and the stability of the suspension due to the cooperation of the frame and hip belt.

First, when comparing the comfort of each model, the Gossamer Gear Gorilla 40 was particularly excellent compared to the other models. The aluminum frame and pads fit just right into the back, while the shoulder and hip belts are thick, 3D Air Mesh that relieves weight. THE NORTH FACE Kyles 35 which has a trampoline-structured back, is also extremely comfortable to the back.

Next, regarding the suspension stability of each model, the feeling of strain on the body (especially the shoulders) is completely different depending on whether the load is firmly on your back and on your waist, and the difference is clearly reflected by carrying a certain amount of heavy load. Here, we mainly operate the same course for a certain period of time with a capacity close to the limit load of the pack, comparing the comfort and ease of fatigue of each. We packed the luggage (approximately 8kg) as shown in the photo below, assuming that we would stay in a solo tent for 1 night in Okuchichibu in September. Of course, there are people who use the authentic Ultra Light equipment to stay under 5kg even when staying in a tent, but please understand that this time we are only assuming that it is "light enough to be too light enough to be overwhelmed."

The best here is THE NORTH FACE Kyle's 35 , Mountains and Roads ULFramePack ONE . The TNF (although I could have predicted to some extent), the incredibly sturdy aluminum frame and the hip belt that are almost directly connected to the frame make it structurally weigh on your waist no matter how much it is. On the other hand, the mountains and the roads have a rigid and flexible X-shaped carbon frame that is tightly attached to the body using stabilizers on the shoulders and waist, and the center of gravity is placed on the waist. The convenient feature of this structure is that if you loosen the stabilizer on your waist when carrying light luggage, it will make it easier to carry on your shoulders and run, and this versatility is a highly rated point that you wouldn't find in other models.

Incidentally, if the model is below 16 comfort rating, the burden on the shoulder cannot be ignored in cases of heavy loads. For this reason, people who often take on luggage that exceed 8kg should be careful to choose a model that is underrated for this category.

Mobility

Fastpacking and speed hiking, which are sometimes fast or run, are often required to carry it when walking leisurely, as well as mobility in the sense that even during intense exercises, the backpack can act comfortably without interfering with movement. With this mobility, I mainly tried running on the trail while carrying a weight of around 3kg, and evaluated two points: ease of movement (= fit, ease of swinging your hands and feet, and how unshaking the pack is) and breathability of the pack.

As you can imagine, the ULTIMATE DIRECTION Fastpack 30 . The harness is fully equipped with the know-how of a brand known for its authentic vest for adventure racing, and is worn with two sternum straps and a strap on the side to hold the top of the chest, making it sufficiently secure even without a hip belt (only for light luggage). Above all, the freedom of the lower body that this mechanism provides gives you the ease of movement that none of the models can suit. The pads are breathable, and are definitely sturdy, making them a perfect pack for running.

Other than that, the MILLET Venom 30 and THULE Stir 35L are very mobile despite the same structure as a regular backpack. What's common to both is that the pack has a slim shape and a high hold around the shoulders makes it less likely to shake against movement (the Venom has a wide shoulder strap, while the Stir has a shoulder strap that works well). Another factor in the high praise is that it maintains high breathability on the back, shoulders and hips.

 

Storageability

This lightweight backpack has been designed to provide a high storage capacity with a compact body, and can be said to be characterized by its extremely flexible exterior pockets compared to a regular backpack. This section compares and evaluates the presence or absence of such pockets and ease of use as storage.

When comparing the 10 models, the main points we evaluated were the following:

• canopy
• Front pocket
• Side pocket (side strap)
• Hip belt pocket
• Shoulder belt pocket
• Hydration Pocket
• Pole (ax) holder
• Other attachments

The Montane Ultra Tour 40 covers almost all of the above storage spaces except for the canopy, and is also as light as possible, yet at a high level without compromising durability and ease of use, making it an absolutely excellent model in terms of storage capacity (the very disappointing thing about this model is how comfortable it is when you make a large amount of luggage by making full use of these storage spaces). Other MILLET Venom 30 and THE NORTH FACE Kyles 35 are also well-crafted and carefully designed. This storage is a safe storage system that combines lightweight, easy-to-use pockets with a standard backpack and the same level of storage.

Functionality

The last evaluation item for lightweight backpack is functionality. However, even though it is called a function, it is difficult to define, so please consider it as an item that combines elements other than the above that affect the usability of the pack. Specifically, the following points are evaluated using each model:

• Easily open and close the main compartment
• Direct access to the main compartment
• Rear adjustment function
• Back mat included
• Can parts be separated to reduce weight?
• Waterproof care such as rain covers and waterproof fabrics
• Are there any areas where durability is extremely uncertain

All of these things were highly rated the THULE Stir 35L , which stands out from the rest, as it offers convenient features such as a drawcord that can be opened and closed, a zipper that allows direct access to the main compartment, a rear adjustment function, part separation, and a rain cover.

Another thing to note is that it is difficult to find the same robustness as conventional backpacks, and as this is environmentally limited, this test does not focus on durability testing. In fact, during testing, there were no models that seemed to be difficult to maintain as the central part of the backpack. However, there are some areas that are normally used and seem unbearable to the minimum level of use, and these points are evaluated as deductible in this category. Specifically, the fabric used for the straps of the ULTIMATE DIRECTION Fastpack 30 and Gossamer Gear Gorilla 40 It's fluent and difficult to use (it quickly turns over), and it quickly cuts too much. This is something I really hope for improvement.

It is not necessary to have all of these items as a guideline, so it is best to have the score determined by checking a list to see if it has the functions necessary for you.

summary

This time, we compared models from garage makers that are usually difficult to obtain with models from Maspro makers that are easy to obtain nationwide, and we were able to see that the ultralight backpack from garage makers is not only easy to use, but also performance and functionality exceeding Maspro makers' models.

Of course, this is not to simply say that garage manufacturers are better products, and situations that have not been tried this time, price and ease of purchase (or more than anything, whether they can try on the product) are important comparison factors, and it goes without saying that each user must judge the superiority or inferiority of a product from a multifaceted perspective.

Lightweight backpacks are extremely easy to use as long as they match your purpose and usage. However, as revealed in this comparison, while there are highly versatile models with the potential to be used in a wide range of ways, from ultralights and trail runs to general traverses, there are also models that place a considerable center of gravity on specific activities. When considering these models because you think, "A light backpack is definitely better," it is important to know the differences in these features and then choose the model that suits your preferences.
