Suspension System

The suspension system is the heart of every backpack. It makes the key difference when it comes to comfort and fit. VAUDE backpacks are high performance products that are truly versatile.



The suspension system is the direct connection between you and your gear, so it’s the most important component of your pack. Carrying comfort is important because it allows you to concentrate on your performance and enjoy your adventure to the fullest. VAUDE suspension systems are multi-functional. Nevertheless, we offer different suspension systems that are fine-tuned to different activities so you’ll always have the perfect gear for the conditions you face. Depending on your activity, you can choose a full-contact back or a ventilated suspension system.

What the suspension system must be able to do

An excellent suspension system fully distributes the weight of your pack across your back evenly so that it doesn’t affect your center of gravity while hiking. It’s responsible for comfort, stability and the fit of your pack, so even with a heavy load it should never pinch or cause sore spots. In addition, it should provide protection and enable good air circulation between the pack and your back.

What to watch for when trying it on

A pack only provides optimal support when it’s matched to your own specific needs. This also means that it doesn’t restrict your freedom of movement. So you should really pay attention to ensuring a perfect fit when you’re trying on a pack.


VAUDE offers backpack models in every volume range and for every activity – from climbing to hiking to backpacking. Thanks to different adjustment options, you can always adapt the backpack to your individual needs and ensure that it’s stable and balanced on your back, even during high-motion activities.

Torso length

Some people are short and small, others are big and burly. Every person has an individual torso length and shape, which is why a backpack must be able to be adapted to these anatomical conditions. We offer trekking backpacks (models Astrum EVO and Skarvan) in three different torso lengths for your individual needs, so that you can find your own custom-fitting backpack. Based on the standard values on our user-friendly VAUDE size chart, you can easily find out which back length is right for you. Of course, these recommendations aren’t a replacement for trying on a pack in person at a trusted VAUDE specialty shop. You can also easily determine the length of your torso yourself.

The distance between two points is used to measure torso length (upper point = 7th vertebrae / upper edge of shoulder blade, lower point = upper edge of pelvic bone). Generally, backs are divided into short (40-49 cm), medium (50-57 cm) and long (58-69 cm).

Adjust back length correctly: Shifting Back Length


“Shifting Back Length” means the pack can be precisely
adjusted to the wearer’s torso length – for extra comfort
on your tour.

In comparison to the F.L.A.S.H. technology, here not only the length of the shoulder straps is adjusted, but also the complete back length.

Adjusting the straps correctly


You can adjust the straps using the F.L.A.S.H. technology. For an optimal fit, the end of the shoulder strap should be just below your chest (see illustration below).

ADJUSTMENT You can easily and quickly adjust the straps to fit your torso length by using the Velcro strap at the bottom of the suspension system. Open the Velcro strap so that you can adjust the length of the shoulder strap unit (1). Adjust the strap by pulling it out or pushing it in to reach the right length (2). Reattach the Velcro strap to secure the position. Size markings on the outside of the Velcro strap can help you determine the correct length.

Here are a few tips to help you adjust your pack correctly when it’s fully loaded:

  1. Loosen the shoulder straps and the load positioning straps.
  2. Put on the pack and close the hipbelt. The hipbelt should sit snugly on the top of your pelvic girdle.
  3. Then stand up straight and slowly tighten the shoulder straps until they fit snugly on your shoulders without the pack pulling upward when you bend forward.
  4. If your pack has them, tighten the load positioning straps and close the sternum strap. The sternum strap determines the distance between the shoulder straps.



Backpacks with full contact backs are highly functional mountain and climbing backpacks and were primarily developed for activities in demanding alpine terrain (via ferrata etc.).

The pack lies directly against your back and distributes the load evenly while keeping your center of gravity as close to your body as possible. This improves your balance and maximizes your freedom of movement.

Synergy Mold

Backpacks with the Synergy Mold back system are designed for mountaineering and ski touring in demanding terrain. The system convinces with its stability and body-hugging fit. Large-volume models offer packing stability and optimum carrying comfort thanks to an adaptable aluminium frame. Small volume models allow optimal load transfer and packing stability through an integrated, ergonomic back plate.

Synergy Mold Light

Backpacks with the Synergy Mold Light suspension system were designed for alpine climbing and mountaineering in demanding terrain. The system is lightweight and offers maximum freedom of movement. A large ventilation channel that runs along your spine helps air circulate. Adjustable aluminum stays or an aluminum frame ensure stability and good wearing comfort (not used in all models).

Vent Active Hike

The Vent Active Hike suspension system provides stability and freedom of movement on day trips with lightweight to normal gear. An ergonomic back panel (EMP) ensures for even load distribution and high pack stability. Ventilation channels in the padding keep air circulating effectively.



Rear-ventilated suspension systems create an open space between the pack and your back where air can circulate freely from three sides. The pack doesn’t lay directly against your back – a mesh panel creates distance between the two, providing maximal ventilation. Rear-ventilated suspension systems are the best choice for sweat-inducing, strenuous activities.


Aeroflex suspension systems offer the best ventilation for backpacks. A stable mesh panel is attached to an extremely lightweight spring steel frame. The taut mesh ensures sufficient space between your back and the pack. It creates a generous ventilation space with optimal 3-way air circulation (from both sides and from underneath) for your back. The suspension system fits perfectly against your back no matter what your activity.

Backpacks with the patented Aeroflex suspension system are perfect for hiking trips that require greater back ventilation. The center of gravity is, however, farther out than it is with other packs that lie flat against your back.

Aeroflex 3D


Aerolflex 3D is the further development of our classic Aeroflex back. The range of application is exactly the same, but the performance of the back has been significantly increased.

The construction allows ventilation from all sides. This reduces heat build-up on the back by up to 42%* and moisture formation by up to 23%*.

* In comparison to reference backpacks, confirmed by a study of the University of Applied Sciences Technikum Wien.


Aeroflex Control

For backpacks with Aeroflex Control, the rear-ventilated back can be converted to a full contact back. The ventilation space at the back can be fully adjusted. More distance = optimal ventilation, less distance = better balance because the center of gravity of your pack is closer to your own center of gravity. This makes these packs truly flexible for all kinds of activities.



Our trekking and travel backpacks are designed to carry a lot of gear and heavy loads over long distances. Carrying comfort is ensured with optimal adjustment based on your individual back length.

A poorly fitting backpack can not only spoil the fun on your trip, it can also lead to tension and back pain. A well fitting backpack is easier to carry because the load is ideally placed on the hips and shoulders, so less energy is needed to carry it.


The Tergolight suspension system was specifically developed for multi-day tours or short trekking routes. It offers the perfect combination of light weight and comfort. The back length can be adjusted exactly to your personal needs. An integrated spring steel frame ensures optimum load distribution and stability.

Tergolight Comfort

The “Comfort” version of the Tergolight suspension system is suitable for long tours with a lot of gear and offers maximum comfort even when carrying heavy loads. The back length can be precisely adjusted to your torso length. Two integrated frames (spring steel and aluminum) ensure stability and distribute heavy loads optimally on the back and hips. The shoulder straps and hip belt feature a smooth material that’s comfortable to wear, even over longer periods.



We use many different technologies in our VAUDE backpacks for optimal functionality. Below you will find a brief overview of the most important technologies that make our products so unique.


Your height and the length of your torso are important criteria for the optimal fit of a backpack. F.L.A.S.H. stands for Floating Length-Adjustable Shoulder Harness and it’s a patented system for adjusting the length of your backpack straps. The mechanism offers continuous adjustment for a perfect fit to the length of your torso.

EMP (Ergonomic Movement Panel) is a lightweight, ergonomic back panel. It provides your pack with stability and even load distribution. At the same time, the panel ensures freedom of movement (for example, rotational movement in the upper section) so that you can react quickly in demanding terrain.


Thanks to a 3D knit construction that’s unparalleled worldwide, VAUDE backpacks are manufactured at a quality level that’s never been experienced before: The production process is gentle on the planet because the foam-free back section doesn’t produce any waste. The seamless construction ensures exceptional comfort and a perfect fit, making this vest-type suspension system perfect for high motion sports. Pressure distribution and ventilation is optimized by the special positioning of a variety of densities at the back.

Aluminum frames

In order to ensure an even more precise fit, some VAUDE backpacks with body contact backs have aluminum stays or aluminum frames that can be removed and individually adjusted.

Ergo Shape Shoulder Straps


Ergo Shape shoulder straps are ergonomically designed to improve your freedom of movement. The straps are wider at the top of the shoulders to provide increased wearing comfort. They are especially narrow at the shoulder joints so that they don’t restrict the natural freedom of movement.We use adapted variants of the Ergo Shape shoulder straps for both ladies’ and men’s backpacks.
