Technologies used

In this chapter we explain the technologies that the manufacturer uses for this product.

deuter Aircomfort
Deuter relies on maximum ventilation for backpacks with a small to medium volume that are used in easier terrain. The indestructible heart of the Aircomfort systems is the permanently elastic spring steel frame. It gives the airy special net its stable tension even under load and thus creates a ventilation space between the rucksack and back through which the moist air can escape unhindered.

The result: up to 25% less sweating thanks to the maximum ventilation of the Aircomfort mesh back system. This ensures less circulatory stress and thus more endurance - scientifically tested by the renowned Hohenstein Institute.

600D PES
Woven from 600 denier polyester yarn and with a thick PU coating, the tear-resistant and light fabric can be used universally. When it comes to keeping the weight of the rucksack as low as possible with moderate use, this is the ideal choice. The "Deuter-Super-Polytex BS" variant is produced according to the strict Bluesign standard. Their equipment and resilience are identical.

210D PA
Deuter uses the robust polyamide textile in 420 denier and 210 denier. This fabric is very abrasion-resistant due to its extremely high weave density. The high-quality material is used in Guide backpacks, the Futura series and models in the Travel series. It has a fine texture and a technical look. PU coated.

SL Women`s Fit
This model is available as an SL version. The SL back length that is specific to women can already be seen in the back length: on average, women have a back that is not quite as long as men. The carrying system of the SL models is therefore a little shorter than that of the Deuter standard backpacks. In addition, the carrying system is specially adapted to the female anatomy.
