The reduced contact surface of the deuter Airstripes back system and airy, quick-drying Air Spacer Mesh against the back combined with perforated shoulder straps and hip fins ensure maximum airflow, even weight distribution, excellent comfort and a snug, secure fit on multi-day via ferrata (fixed-rope) routes.  Loops on the shoulder straps keep via ferrata set carabiners close at hand. And thanks to a large front zipper opening and stretch side pockets, equipment and gear are always easy to access, or can be stashed in the separate bottom compartment.

Top features of the Trail Pro 31 SL

SUPERIOR VENTILATION FOR A DRY BACK

The Airstripes back system with reduced contact surface and new, airy, quick-drying Air Spacer mesh is combined with perforated shoulder straps and hip fins to ensure not only maximum airflow but also fits snugly to the body for compact weight distribution – for a significantly more comfortable carry on any terrain.

SAFE ON VIA FERRATAS

Loops on the shoulder straps keep the carabiners of the via ferrata set close at hand. That, combined with the backpack’s compact, snug fit provides enhanced safety when climbing fixed-rope routes. 

PRACTICAL FEATURES FOR FAST ACTION

Thanks to a large front zipper opening and elastic front stash pocket, equipment and gear are always readily at hand, yet compactly stowed.

SL Women’s Fit

This model is also available in the SL version. The SL back length is specific for women: on average, women have shorter backs than men. The carrying system in the SL model is therefore somewhat shorter than in the Deuter standard backpacks. In addition, the carrying system is specially adapted to the female anatomy. More information about our . 

Our unique Airstripes System takes care of that and offers effective ventilation. It consists of two contoured, air-channelled foam profiles that are covered with a highly breathable Wide AirMesh lining. The reduced contact surface results in an optimized fresh air circulation. Also, the pack’s load is kept close to the body and thus won’t throw the rider off balance.

THE RESULT:

The minimal contact surface area of the profiled Airstripes allows free air circulation over 80 % of the back, while still providing a secure, compact fit.

PFAS free

This deuter product is free of intentionally used PFAS (per- & polyfluorinated chemicals). deuter thus reduces the use of substances, that are known to harm the environment and health.

For Outdoor products PFAS are mainly used for water repellant treatments.

Instead, deuter uses since 2019 alternative DWR (Durable Water Repellency) impregnation.

100% recycled PET material

The fabrics used for this model are made of post-consumer PET bottles.
