Comparison Criteria
The Most Important Evaluation Criteria
To evaluate both brands fairly, clear and understandable criteria are needed. These should always be considered in their entirety.
Pack Volume and Expandability are crucial for how much gear and game meat can be transported. For day hunts, backpacks with a volume of 30 liters are often sufficient. However, those planning multi-day trips in remote areas often need 40 to 65+ liters – ideally with options for expansion to securely store meat [1][2].
Carrying comfort under load: As already mentioned, the carrying system becomes particularly important from a weight of 25 kg. A well-thought-out hip and back system ensures that the weight is shifted to the hips and remains close to the body's center of gravity. This especially spares the knees and ligaments during long descents. A fitting quote from a hunting forum puts it succinctly: “Physics applies to everyone!" [1].
The empty weight of the backpack directly influences the usable payload. A heavy empty weight, such as the 3.84 kg of the Exo K4, reduces the capacity for additional equipment or game meat [1].
The noise generation also plays an important role. Backpacks with many plastic buckles or MOLLE loops can be disruptive during stalking or sitting in quiet forests [2].
Modularity is another criterion that allows the backpack to adapt to different hunting situations. Whether for a short day hunt or a multi-day expedition – a modular system offers flexibility. However, this can also mean more weight and potentially higher noise generation [2].
Finally, durability under extreme conditions is not only a matter of comfort but also of safety – especially during demanding hunts.
How these criteria fit hunting in Germany and Europe
Once the most important evaluation criteria have been clarified, the question arises as to how these are specifically relevant for hunting in Germany and Europe.
The requirements vary greatly depending on the type of hunting and terrain. For chamois hunting in the Alps or reindeer hunting in Scandinavia, a stable carrying system for loads over 25 kg and a reliable weapon attachment are essential. This allows for hands-free use of the trekking pole [1]. In regions with rapid weather changes, integrated rain covers and water-repellent materials are indispensable [2]. Particularly important for European hunting are modularity and noise generation: An overly loud or difficult-to-adjust system can be a disadvantage during stalking or in the mountains.
The following table shows which criteria are particularly important in the European context:
| Criterion | Relevance for Europe | Why it matters |
|---|---|---|
| Meat shelf | High (Alps, Highlands) | Separate storage of game meat and equipment [1] |
| Noise level | High (Stalking, Sitting) | Quiet materials prevent scaring off game [2] |
| Frame stability | Critical (Mountain terrain) | Prevents the center of gravity from slipping during descents [1] |
| Weapon attachment | High (all types of terrain) | Allows free hands for safety and trekking pole [1] |
| Own weight | Medium | A lighter backpack creates more capacity for game meat [1] |
For lowland hunting in Germany, such as during driven hunts or short stalking trips, the requirements are less demanding. Often, a simple daypack is sufficient, as a complex carrying system can be oversized for lighter loads [2]. Additionally, many German hunters prefer neutral colors like olive, stone gray, or brown, so that the backpack does not stand out off the hunting grounds [2].
The next section will examine how these criteria are reflected in the products of Mystery Ranch and Stone Glacier.

Mystery Ranch Backpacks

Brand history and design philosophy
Mystery Ranch was founded by Dana Gleason, an experienced developer in the field of backpack design. Before founding the brand, he worked on carrying systems for US special forces and wildland firefighters – an expertise that is still reflected in the products today [6]. The brand's main focus is on durability and functionality. Many models are based on the Guide Light MT Frame, a sturdy frame system specifically designed for heavy loads. This is complemented by the patented Futura Yoke, an adjustable carrying system that allows for precise adjustment of the back length [4].
The most important models and their features
On this solid foundation, Mystery Ranch offers a selection of models designed for different requirements. Here are some of the central models:
| Model | Volume | Application area | Special feature |
|---|---|---|---|
| Pintler | approx. 38.6 L | Day hunting / 1–2 nights | 3-ZIP design, quiet material |
| Metcalf | 50–100 L | Multi-day expeditions | Versatile, high capacity |
| Beartooth | 85 L | Long tours, mountainous terrain | Maximum volume, 270° access |
A special highlight is the Overload feature. This additional loading compartment is located between the frame and the backpack and is ideal for transporting bulky equipment or game meat directly on the back. Hunters especially appreciate this function as it allows for quick and ergonomic transport of game [4][5].
“The hunter puts the rabbit or the boar in the Overload shelf and carries it home." – User “Steuermann”, Bushcraft-Germany Forum [5]
Another practical detail is the 3-ZIP design of the Pintler. It allows for quick access to the main storage space – a significant advantage when quick access to equipment is needed in the field [6]. With a weight of about 2.5 kg and a volume of 38.6 liters, the Pintler is the most compact model in the series [4].
Strengths and Weaknesses
Mystery Ranch excels particularly in demanding applications, whether on long mountain tours, carrying heavy loads, or in challenging terrain. The use of 500D Cordura, YKK zippers, and Autolock buckles ensures extreme durability [4]. In hunting forums, the brand is often referred to as a leader in terms of craftsmanship and reliability.
However, there are also limitations: For lighter applications, such as hunting in flatlands, the backpacks might be somewhat oversized due to their robust construction [2]. Additionally, the models are priced in the upper segment [5][6].
Stone Glacier Backpacks

Brand History and Design Philosophy
Stone Glacier was founded in 2012 and specializes in ultralight, functional hunting backpacks [11]. The brand targets hunters who operate in high alpine regions and need to manage heavy loads. The central element of their backpacks is the Xcurve frame, made from curved carbon rods. This frame adapts to the natural curvature of the back and ensures optimal weight distribution. Both the Xcurve and the Krux systems are flexible and can be adjusted to different back profiles [8][11]. This philosophy is consistently reflected in the core models of the brand.
The most important models and their features
An outstanding model is the Sky 5900. With a main compartment volume of about 88 liters, it offers plenty of storage space, which can be expanded to over 140 liters with an optional lid pocket and the integrated Load Shelf – a loading compartment between the backpack and frame – [7][8][10]. The Load Shelf is specifically designed to carry loads of more than 68 kg, which is ideal for transporting game close to the center of gravity without taking up the main storage space. Additionally, the backpack can be compressed to about 65 liters in Bivvy Mode, making it flexible for switching from multi-day to day use [7][11].
| Feature | Sky 5900 (Xcurve, Medium) |
|---|---|
| Weight | approx. 2.5 kg |
| Main Compartment | approx. 88 liters |
| Bivvy Mode | approx. 65 liters |
| Load Shelf | approx. 41 liters |
| Maximum Load Capacity | over 68 kg |
| Material | 500D Cordura / Xpac |
Strengths and weaknesses
Despite its innovative features, there are also some weaknesses. The Sky 5900 particularly excels at handling heavy loads. Øystein Cock Rønning from the Norwegian magazine Jakt & Fiske reported after a test with over 40 kg of load:
„This is the first pack I have used that does not give me stiff shoulders after the first day of carrying." [10]
The Scandinavian hunting magazine Jakt rated the Sky 5900 in issue 6/2021 with 10 out of 10 points and named it “Best in Test” for reindeer hunting [9]. It is also a suitable choice for hunting chamois or mouflon in the Alps.
However, there is also criticism: The many straps and buckles can make switching to load mode in the field more difficult [10]. Additionally, it is often noted that the lid does not always sit securely due to the long attachment straps [7]. In terms of price, the Sky 5900 starts at around 659 US dollars in the USA, while it costs about 8,999 NOK in Norway – thus positioning itself clearly in the premium segment in the German market [7][10].
Mystery Ranch vs. Stone Glacier: A Comparison
Carrying Comfort and Load Capacity
In direct comparison, it becomes clear: Stone Glacier is excellent for heavy loads, while Mystery Ranch scores with precise adjustment options. Sean McCoy, Editorial Director at GearJunkie, sums it up well:
“The purchase price might sting, but not as much as a bad backpack while hauling quarters." [7]
The differences in the carrying systems also affect the weight and modularity of the models.
Weight, Modularity, and Hunting Features
In terms of weight, the two models are nearly equal: The Metcalf 75 weighs about 2.6 kg, while the Sky 5900 is around 2.5 kg [3]. The difference lies in modularity: Stone Glacier offers the Load Shelf feature, allowing the main storage space to remain clear, which facilitates the transport of harvested game. Mystery Ranch, on the other hand, relies on the piggyback system, where the Gravelly 18 backpack can be directly attached – ideal for short distances or the final stalking section.
Durability, Price, and Overall Value
Both models are made from durable 500D Cordura, designed for use in rugged terrain. In independent tests, the Sky 5900 scored better with a rating of 9.2 out of 10 compared to the Metcalf, which achieved 8.0 out of 10 [3]. Durability and functionality were particularly highlighted.
| Feature | Mystery Ranch Metcalf | Stone Glacier Sky 5900 |
|---|---|---|
| Weight | approx. 2.6 kg | approx. 2.5 kg |
| Main Volume | approx. 4,335 cubic inches | approx. 5,900 cubic inches |
| Max. Load Capacity | high (no official specification) | over 68 kg |
| Modularity | Piggyback system (Gravelly 18) | modular interchangeable compartment + Load Shelf |
| Test Rating | 8.0/10 [3] | 9.2/10 [3] |
| Price (USD) | from $549 [3] | from $725 [3] |
With a price of about $549, the Metcalf is significantly cheaper than the Sky 5900, which is around $725 – both prices without accessories. Those looking for a versatile, robust system at a lower price will find it with Mystery Ranch. For hunters who regularly transport heavy loads over longer periods and are willing to invest more, Stone Glacier offers a more thoughtful overall package.
Hunting in Germany: How well do the backpacks fit?
Fit for different German hunting styles
The question of how the backpacks perform in typical German hunting situations is crucial. During a sit-and-wait hunt, the Mystery Ranch Pintler scores with its 3-ZIP system, which allows quick access to the main compartment. For stalking, where distances of 10–15 km are often covered, the high-quality carrying system provides constant comfort. In mountain chamois hunting, the Overload system from Mystery Ranch stands out: the game can be stored between the frame and the backpack, keeping the center of gravity close to the body. At the same time, the hands remain free, for example, for using a trekking pole. These different requirements reflect the versatility that should be considered when choosing the right backpack for hunting in Germany.
Compatibility with European hunting equipment
Both brands offer MOLLE/PALS attachment points that allow for the external attachment of accessories such as shooting sticks, tripods, or binoculars. This ensures that the main storage space remains unused. High-quality optics like a Zeiss Victory RF or a Swarovski EL Range can be conveniently secured in side pockets or attached to MOLLE pouches. When transporting firearms in Germany, it is important that they are secured and not ready to fire. Many hunters use either the main compartment or the space between the frame and the bag for this purpose. Since most German hunting loads are under 25 kg, a heavy military carrying system can mean unnecessary weight. However, a robust frame is advantageous for multi-day mountain tours or particularly heavy luggage.
Find the right equipment on Gunfinder
On Gunfinder, you will find a wide selection of hunting gear, from optics to rifles – both new and used. The platform allows you to specifically search for accessories that are compatible with the dimensions of the side pockets of Mystery Ranch or Stone Glacier. This way, you can optimally adjust and complement your hunting setup.
Conclusion
The most important differences at a glance
Both brands operate in the premium segment: Mystery Ranch impresses with exceptional durability, while Stone Glacier scores with an excellent weight-to-stability ratio. The Metcalf made from 500D CORDURA receives a rating of 8.0/10 and is awarded as the “Most Durable Big Game Pack”[3]. The Sky 5900, on the other hand, achieves 9.2/10 and impresses with a comfort rating of 10/10[3]. In terms of price, Mystery Ranch is ahead – the Metcalf is cheaper than the Sky 5900, which is positioned in the upper price segment[3]. These differences help in making the right choice for different hunting styles.

FAQs
What volume do I need for my hunt?
The choice of the right backpack volume largely depends on the duration and type of hunting:
- Multi-day trips: Here, backpacks with a capacity of 40 to 70 liters are ideal. They provide enough space to securely store equipment, provisions, and the harvested game.
- Day trips: For shorter hunts, a backpack with 20 to 30 liters is usually sufficient to carry the essentials.
- Steep terrain or large trophies: In such cases, a backpack with at least 50 liters is recommended to comfortably and safely transport everything.
The right size ensures that you are optimally prepared without carrying unnecessary weight.
When is a frame backpack really worth it?
A frame backpack is particularly practical for multi-day hunting trips where larger amounts of equipment, provisions, or game need to be transported. With its stable carrying base and optimized weight distribution, it is excellent for difficult terrain and heavy loads. For shorter trips or lighter tasks, a more flexible backpack is often sufficient. It is important to adapt the choice of backpack to the duration of the trip, the area of use, and personal carrying comfort.
How do I safely transport game meat in the backpack?
A hunting backpack with well-thought-out compartments or padding is ideal for safely transporting game meat. It is important that the meat is stored cool and stable to maintain freshness and hygiene. Models specifically designed for game meat transport offer practical solutions and facilitate safe handling during transport.
