Detailed Description

Versatile two-chamber companion

Two-chamber Activent backpack designed for longer treks or outdoor stays. Its most fundamental difference compared to its smaller version of Activent 48 is the ABS back system. This is a system that allows you to adjust the backpack height in the 10 cm range.

Activent 55 has a large number of straps to hold different loads. Snowshoes or snowboards can be attached to the front of the backpack and the skis can be attached to the sides. There are also two pairs of straps. Also worth mentioning is the strap under the lid of the backpack, designed to hold the climbing rope.

Key Elements

On the lower side of the backpack there are two simple loops for trekking sticks or ice-axes. A little higher, there is a spacious entrance to the lower chamber. At the same level, there are two mesh pockets on the sides. Other important features of Activent 55 include compression straps with buckles and vertical lamelled pockets for equipment.

The front part of the backpack features two horizontal straps with clasps, suitable for attaching a tent, snowshoe or snowboard. On the top strap, there is a velcro loop for attaching trekking sticks or ice-axes, which can be detached.

The upper chamber is fitted with a lid with two pockets, larger at the back and smaller underneath. The top closure of the chamber is made from a pair of strings with brakes. In the chamber we can also find a  loop for attaching the rope and a hydrobag pocket.

Finally, it is important to mention that the chambers are separated by a zipper partition, and a combination of the back and waist belt can be made into lumbar pack.
