55 liter MOLLE external frame backpack with 10 liter E&E pack

The SENTINEL from Zentauron is a robust 55-liter backpack with a removable 10-liter lid. This results in a total volume of 65 liters. The lid was developed as a small additional backpack.

With its outer frame, it is designed as a professional and tactical rucksack for heavy loads (25-40 kg). It can be used as a military rucksack, army rucksack or as a modular hiking and trekking rucksack for leisure.

The volume of the rucksack can be easily expanded with other pouches via the MOLLE system, giving the user the individual freedom to configure their personal rucksack system to suit their specific requirements. Accessory pouches can be attached directly to the rucksack or to the rucksack's hip belt. The removable lid can be used as a small rucksack, for example for the Escape & Evasion function.

The outer frame ensures good ventilation in the back area and prevents heavy sweating and friction. For people wearing protective equipment such as plate carriers or protective vests, there is a further advantage: the rucksack does not press on the lower edges of the protective plate.

The backpack is equipped with padding on the body support surfaces for optimum comfort. The rucksack is made of robust Cordura, the material is FU impregnated and PU coated. The SENTINEL can be filled via two openings. This makes it a top and front loader.

Backpack - the main compartment

The main compartment of the SENTINEL is a combined front and top loader and has a capacity of 40 to 55 liters, depending on the compression of the roll-up closure. This is located under the removable lid. There are pockets on the outside. These can hold drinks, canteens or other items of equipment, for example.

Top-loading rucksack

One option for loading and removing equipment is to use the top opening, which is fitted with a roll closure.

The roll-top closure offers several advantages. On the one hand, the contents can be ideally compressed and bring stability to the rucksack. Secondly, this type of closure ensures that the contents are protected from dust and moisture.

The principle of the roll-up closure is simple and effective. The upper end is pulled apart at the two plastic plugs and rolled up several times. The plugs and housing are then pushed together. This secures the closure.

Front loader backpack

The second option for loading and removing the equipment is to use the front opening. This opening can be partially or fully opened with a double zipper over a length of 18x50 cm. This allows the user to easily access items of luggage located in the lower section of the rucksack.

On the inside of the front loader opening, a lid compartment with a zipper is sewn into the entire surface. Smaller items of equipment that need to be quickly accessible can be stowed here. The zipper is protected from dirt and damage by overlapping fabric.

MOLLE system of the tactical backpack

MOLLE loops are sewn onto the front of the SENTINEL to which additional equipment can be attached. They can also be used to attach lashing straps. Above the opening of the front loader, optional accessory pouches can be attached to the MOLLE on an area of three horizontal rows and seven vertical channels.

There are five horizontal rows on the zipper opening of the front loader for attaching additional pouches with MOLLE in four vertical channels. They are also suitable for attaching the side compression straps.

Below the opening of the front loader, there are four horizontal rows on the left and right for attaching additional pouches in two vertical channels with MOLLE.

On the underside there are two horizontal rows with two channels on the left and right. Smaller bags, sleeping bags or sleeping mats can be attached here with MOLLE.

MOLLE holder for side pockets

If additional space is required, further pouches can be attached to the MOLLE mounts on the sides of the backpack. The attachment surfaces on each side have six horizontal rows with five channels of MOLLE loops.

This means that the packing volume of the SENTINEL can be further increased individually. For example, the Zentauron combat bag can be attached to the sides. With this extension, it is possible to increase the maximum volume of the main compartment from 55 to 72 liters.

The carrying system with external frame

The best way to carry heavy loads comfortably over a longer period of time is to redistribute the load. This involves shifting the load from the shoulders to the hips. For this purpose, a frame (outer frame) has been integrated into the backpack system.

The carrying system supports the load distribution and is particularly advantageous for wearers of protective equipment, protective vests and/or plate carriers. The frame ensures sufficient distance from the back. This prevents chafing on the protective equipment and at the same time ensures good ventilation, which minimizes perspiration.

The padding at shoulder blade height ensures a comfortable fit on long marches. The outer frame is made of sturdy plastic and reinforces the back area over a length of approx. 50 cm. This increases the stability of the rucksack and distributes the weight on the hips.

Padded hip belt

The padded hip belt is firmly attached to the outer frame and transfers the weight from the backpack to the hips. The hip belt is fastened with a 40 mm wide webbing and a robust plastic buckle. The webbing is equipped with a "pull forward" loop for tightening. The circumference of the hip belt can be adjusted from 80 cm to a maximum of 120 cm.

Modularity on the hip belt

For smaller items of equipment and pouches, there are three horizontal rows with five vertical channels for MOLLE attachments on each side of the hip belt. For example, small multi-purpose pouches or Medic pouches can be attached. They can be accessed quickly during a march.

Shoulder straps

The approx. 7 cm wide shoulder straps ensure good weight distribution on the shoulders and are also padded. For optimum load distribution, there are load control straps on the shoulder strap that are connected to the rucksack.

The load control straps should be at the height of the collarbone and fixed at an angle of approx. 20 - 30° to the rucksack. A pulling aid at the end of the shoulder strap makes it easier to tighten when putting on the SENTINEL.

Chest strap

The chest strap provides additional stability when carrying. It can be positioned almost anywhere on the strap of the shoulder strap. The length of the chest strap can be adjusted using three bars and a plastic buckle.

Lid compartment as a 10 liter Escape&Evasion pack

The lid compartment not only serves as additional storage space, but is also an escape & evasion pack with a capacity of approx. 10 liters. Items such as rainwear, maps, glasses or survival kits can be stored here.

The special feature of the SENTINEL is that the lid compartment can be detached from the main rucksack using the buckles provided, making it a small rucksack or E&E pack (escape rucksack). This gives the user the freedom to be independent of their main pack.

There are also Molle loops on the top to attach additional equipment or Molle pouches.

On the front there are five rows and six channels of MOLLE to which other multi-purpose pouches, such as our 'Horizontal' or 'Quadro' multi-purpose pouch, can be attached.

There is a 5 x 10 cm Velcro surface for labeling. Patches or name tapes can be attached. The lid compartment consists of a main compartment equipped with a double zipper. There is another small zippered compartment on the back of the lid compartment.

The lid compartment is compressed using an elastic cord with cord stoppers attached to the top and sides.

The lid compartment is attached to the rucksack using 4 buckles. When the lid compartment is detached from the rucksack, the four buckles are free to accommodate the carrying straps supplied. The lid compartment then becomes a small backpack with a capacity of 10 liters. The carrying straps can also be used as rucksack straps.

The Sentinel can be used as a tactical-military rucksack, but is also ideal as a hiking or trekking rucksack.

funktioniert auch mit Plattenträger

Zentauron hat hier einen tollen Rucksack produziert. Er hat viel Platz und alles, was für 2-3 Tage im Außendienst benötigt wird, hat Platz. Die Verarbeitung ist top. Durch das Außengestell ist es möglich einen Plattenträger zu tragen ohne, dass der Rucksack auf die Unterkante der Platte drückt. Der Rucksack trägt sich sehr angenehm auch auf längeren Fußmärschen. Der Service bei Zentauron ist ebenfalls hervorgagend. Der Preis ist gerechtfertigt.

Gewohnte Zentauron - Qualität

Der Rucksack macht einen soliden und qualitativ wertigen Eindruck. Er hat mich inzwischen auf eine Lost - Place Tour mit Übernachtung begleitet, und sich dort bewiesen, Ob als Lastenträger oder Sitzgelegenheit. Das Tragegestell ist sehr leicht auf die jeweilige Person anzupassen, und ist dank der Bauweise sehr komfortabel. Die einzigen Mankos für mich persönlich sind die Stabilität des Rucksacks wenn er leer ist, sowie die Modularität, z.B. die Möglichkeit kleinere Organizer - Pouches o.ä. im Innenraum anzubringen. Das Hauptfach ist eben nur ein großer Stauraum. Nett gemacht hingegen ist das Meshfach welches in das Öffnungsfach des Frontloaders eingenäht ist.


Alles in allem begeistert Zentauron mit (in meinem Fall) einem Wahnsinns Kundenservice, sowie einer 1A Produktqualität.

Endlich einer für alles

Zentauron hat als einer der wenigen Hersteller die Wünsche von Anwendern erhöht und einen Rucksack in der 55 Liter-Klasse vorgestellt, der wirklich kaum Wünsche offenlässt.
Vom Deckelfach, das sich ohne weitere Riemen (wie z.B. bei Berghaus) als Daypack verwenden lässt über MOLLE am Hüftgurt bist zur Kombination aus Top- und Frontloader passt einfach alles zusammen.
Der Roll-Up Verschluss wie bei den Ortlieb-Beuteln sorgt dafür, dass auch bei geringer Füllung nichts herumschlackert.
Der einzige Wunsch wäre noch eine Durchführung für den Schlauch eines Trinksystems, aber dank des Tragegestells kann das Camelback auch auf dem Chestrig oder Plattenträger bleiben ohne zu drücken.
Gut durchdacht und den Preis absolut wert.
