The support system from Jack Wolfskin combines various different features to enable a great fit on your back.  The Ergo-Dynamic system gives you full control over your backpack in all conditions during your adventures.

Maximal Movement Comfort. Improved Weight Distribution. Comfortable To Wear. Great Performance

  All of these benefits are combined in the rucksack to make it your ideal companion.

Butterfly Back

Often, shoulder straps on rucksacks are attached tightly the back of your spine, however this sometimes proves a problem as everyone is a different size. But with the butterfly back you can adjust the rucksack to your own individual size and also adjust the shoulder straps. The backpack then automatically adapts to the neck width too. hoehenverstellung  

Removable Back Cushion

Padding in the lower back optimizes weight distribution between your shoulders and hips. With the height adjustable back cushion, your naturally curved spine can thus be fully supported. lordosepad  

Weight Distribution

With the EDS system, additional tension belts provide an increased comfort for the shoulders and neck. Straps between the upper compartment and shoulder straps keep the weight balanced.In addition, slipping of the rucksack is also effectively prevented as it is held closer to your body. This gives you increased stability, security in your movements and more power. lastoptimierung  

Individual Hip Wings

With Velcro placed on the hip wings you are able to adjust the backpack and improve the balance of your load. By adjusting these hip wings, you can not only adjust the height, but also change the length. This gives you great freedom for all your movements. flosse   Our Outdoor Expert Julian Lill has been in the mountains, testing the new EDS support system: "I went on a great trek through Hammersbach by the Höllen valley to its peak First of all, I'm really like the rucksack, it was extremely comfortable and a great size for a day trip or overnight stay.

  • 2 bottle holders on the side
  • Extremely adjustable and so very comfortable
  • 2 compartments, one completely waterproof inside with plenty of space for clothes and snacks, and a second compartment which is splash-proof for things that you constantly have to unpack such as a jacket, rope or helmet
  • Good external holders for ice axes and hiking poles with quick access
  • easy accessible upper compartment for keys, sunscreen and or a knife
The only thing that was not completely great were the lateral bottle holders, as they are not easy to get at when walking (too high) and the bottles may fall out while climbing (luckily I tied my bottle so I didn’t lose it) "I like the backpack very much, I'll use it often and would recommend it to everyone."
