The Salomon Sky 25 is a backpack out of the standard classifications, such as trekking, running, mountaineering and so on. It may be defined as a "Crossover". Salomon itself does not categorize it and this is something we agree on and strongly support. In fact, we believe that the constant "labeling" of manufacturers of outdoor clothing and equipment is most of the time unnecessary and it only limits the range of possible uses of a product.

The Sky 25 is a very versatile backpack!

Most importantly, it is very light! Probably one of the lightest backpacks in its category (25l), weighting only 830g!

The fabric used for the outer body is a tear-resistent nylon Ripstop of kind of "shiny" texture, that lets water droplets and snow easily slide on it. The choice of thickness of the outer fabric is a really good compromise between lightness and resistance. The quality of the seams in the most critical points of stress and overall is good, even if it might be a bit lower if compared to some of the direct competitors.

There are a number of clever features that make the Sky 25 a very nice backpack to use. The most important of all is probably the very well designed back system, which in combination with the "bean"-shaped backpack guarantees comfort and enhanced freedom of movement for elbows and arms. The particular shape of the backpack, narrower at the top and bottom, offers another great advantage: when it is fully loaded, most of the weight and volume is maintained well positioned at the center of the back... and even if this may sound something very trivial, believe us, on most other backpacks it is not!


Access to the main compartment and to the two pockets (one on the top and one on the front) is always easy and rapid. 

Two bottle carriers and two ski carriers on the sides, plus two minimalistic pole/ice-axes carriers, all contribute to make the Sky 25 a true year-round backpack.

The back system is composed of a 3D mesh structure that guarantees excellent ventilation and efficiently reduces sweating, even on the hottest days. A particular advantage of the system adopted by Salomon on this backpack is that, at odds with other systems, it doesn't soak up rain and water. 

The shape and structure of the backpack are maintained thanks to a very clever and simple solution: a 2mm-diameter tubular frame of plastic material, which is ultralight, and flexible enough. A pretty nice and smart solution!

The shoulder straps and the waist belt have large portions of airmesh  material that increases both comfort and breathability.

The wrapping of the belt is comfortable, stabilizes the load effectively even during running, and it guarantees full freedom of movement. 

We tested the backpack with loads of up to 15 kg, quite a lot considering its capacity. Even in this rather extreme use, comfort has never failed and the overall structure, the seams, and the plastic buckles resisted very well the severe stress test.


Some clever features:

  • All the regulation straps have elastic rings to keep them in place and avoid fluttering in the wind.
  • The light-colored inside makes the main compartment more luminous. This helps when searching for objects in fainter light conditions.
  • The hydration system compartment is well isolated and this avoids undesired condensation during more intense physical activities, such as running.

What we didn't like: 

  • There are no compression straps on the lower part of the backpack. This causes some difficulties in compressing the load properly. 
  • On the inside, the seams of the zippers seem quite exposed and vulnerable.
