The backpack is very spacious, the color matches the one in the photo, and the carrying system is well designed – even with a heavy load and long periods of carrying, it doesn't cause problems. Definitely worth recommending.
Wisport SilverFox II Backpack 40 l Graphite
Military medium-sized backpack in Graphite color, with a capacity of 40 liters. Equipped with many functional solutions, such as ski mounts and an advanced SAS and OpenBack carrying system with an opening back panel. Made from durable Cordura, equipped with certified buckles ITW Nexus and Duraflex and reinforced stitching. This makes it exceptionally resistant to damage regardless of conditions.
OpenBack system
The backpack features an OpenBack system, allowing access to the interior through a detachable back panel. By unfastening the straps and unzipping the zipper, it is possible to access the entire main compartment of the backpack from the frame side, which is especially beneficial when carrying a large amount of gear. This allows for easy removal or insertion of needed items without having to remove others.
Advanced SAS carrying system
SAS (Semi Adjustable System), being part of the carrying system, allows for adjusting the backpack to an individual silhouette. It includes an adjustable chest and hip belt, effectively transferring weight to the hips and relieving the spine. The straps are attached with buckles and have holders for the hydration system hose. The stitching of the straps and back is made of soft, breathable mesh, providing better ventilation.
Flap closure and extended chimney
The design is based on one large main compartment closed with a chimney flap. The flap is secured with two adjustable straps with Fastex buckles, and the chimney with a drawstring allows the volume of the backpack to be increased if needed. Additionally, the flap has an upper pocket closed with a zipper and a Velcro panel for attaching patches or emblems.
MOLLE/PALS mounting system and ski mounts
The backpack and its interior are equipped with MOLLE/PALS mounting straps, allowing for the attachment of additional pouches and storage pockets. Additional external straps with buckles allow for the transport of larger equipment items, such as a sleeping bag, sleeping pad, or jacket. Open side pockets for a water bottle or thermos and ski mounts are also included.
Rain cover and internal organizer
Inside the backpack, there is an additional organizer with a mesh pocket and a compartment for a hydration system water tank. The double bottom is equipped with a rain cover, providing protection for the backpack and its contents from rain or snow.

Amazing backpack – sturdy, comfortable, and very spacious. During a winter trip to the Tatra mountains, it was comfortable even when fully loaded. The side pockets can fit an Esbit thermos even with a full backpack. The access system from the back is not very convenient – the idea itself is okay, but to reach the inside, you need to unfasten five buckles and a zipper, which is a bit troublesome.

I hesitated for a long time before buying a medium-sized backpack, but the Silverfox II turned out to be a real hit. Well made and high-quality materials. Fits the back very well. Option to attach pockets—including to the hip belt, which was important to me. The backpack opens from the back, so when you want to access the inside, you don't lay it on its dirty side and you don't get dirty again when putting it back on. Thanks to the extension, adjustable flap, and straps on the flap, underneath, and on the sides, you can fit much more than the declared capacity allows. I would give 6 stars if that was possible.

The backpack is solidly made, which is to be expected from the Wisport brand. It has practical solutions, such as a back opening that makes it easier to access the inside without making a mess. Inside, there's an organizer and the option to attach a hydration bladder. On the outside, there are plenty of places to attach additional gear. I have already used the backpack several times during outdoor trips – it is very spacious and comfortable to use. I definitely recommend it.

The backpack is very well made, spacious, and comfortable to use. I've been using it every day for several months and it works great.

It gives the impression of solid construction. Excellently designed – it has an extra pocket on top, can be opened like a suitcase, and the roll-top closure allows you to expand the backpack. There are many options for attaching gear, an internal organizer with Velcro, a sturdy hip belt, and side pockets for bottles.

Excellent, compact backpack for mountain trips. Durability thanks to cordura and military design make it a solid piece of equipment. Lots of MOLLE straps allow you to attach many additional pockets.

The backpack is characterized by high-quality workmanship, which is typical for the Wisport brand. It gives the impression of being extremely durable. A big plus is the ability to fully unzip the backpack, which allows easy access to everything inside. I replaced my Sparrow II 30l with extra pockets with this one, and now all my gear fits without a problem. An excellent choice for BOBA, also in terms of color.

This is the best backpack you can buy. It's very spacious and durable—practically indestructible. The backpack even surpasses Chuck Norris in terms of durability. In addition, the manufacturer offers a great warranty, which makes this a lifetime purchase. I'm very impressed by the quality of these backpacks and the attention to detail. If this one ever breaks, I will definitely buy the same one again. Highly recommend!
