VAUDE Suspension System Technologies

We use many different technologies in our backpacks for optimal functionality.

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.


Here’s a list of the suspension technologies that we use in our products :

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.

Synergy Mold Active

Backpacks with a Synergy Mold Active suspension system are designed for longer bike tours in demanding terrain with a normal load. The system features great breathability and stability. A large mesh insert that runs along your spine helps air circulate and provides effective ventilation for the back. A height adjustable hipbelt offers additional carrying comfort.

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.


EMP (Ergonomic Movement Panel) is a lightweight, ergonomic back panel. It provides your pack with stability and even loads 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.


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.

Adjusting the straps correctly

F.L.A.S.H. stands for Floating Length Adjustable Shoulder Harness. With this adjustment mechanism you can easily adjust the length of the backpack straps.

For an optimal fit, the end of the shoulder strap should be just below your chest. Two systems are used to adjust the height of the shoulder strap attachment:

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. When you open the velcro fastener, the shoulder strap lock is released (1). Adjust the strap by pulling it out or pushing it in to reach the right length (2). Then reattach the velcro. Size markings on the outside of the velcro strap can help you determine the correct length.

Shifting Back Length

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


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

 Tergolight Comfort Space

Comfort Space: Recess at the lower back that can relieve the sacroiliac joint and eliminate back pain. The Tergolight Comfort Space has been designed for tours with a heavy load such as short trekking routes, hut-hopping trips, long-distance trails and backpacking.



  • Individually adjustable back length.
  • Individual adjustment of the upper load position straps.
  • Internal frame made of aluminum that transfers the load directly to the hipbelt.

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 aluminum frames 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.


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 aluminum frame ensures optimum load distribution and stability.


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 and bike tours that require good ventilation of your back. The center of gravity is however farther out than it is with other packs that lie flat against your back.

Aeroflex 3D

The new Aeroflex 3D suspension system allows your back to breathe


Aeroflex 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.

  • Ventilation from all sides reduces trapped heat at your back keeping you drier and more comfortable.
  • The backpack fits perfectly due to a continuously adjustable back length.
  • It’s an environmentally friendly product with 50% recycled materials.

Aeroflex Control

Adjustable AEROFLEX CONTROL suspension system for ventilation on the way up and stability on the way back down


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.

Aeroflex X+

The Aeroflex X+ suspension system is designed for greater adventures and multi-day hiking tours with heavy loads. It features a precision adjustment for different torso lengths and an all-round aluminum frame that ensures stable load distribution. As with all Aeroflex systems, optimum ventilation is a key feature here.

Aeroflex Easy Adjust

For backpacks with Aeroflex Easy Adjust, 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.

VENT-TEX Ultralight

The VENT-TEX Ultralight suspension system was specifically engineered for road biking and mountain biking and/or day trips with a light load. The back panel was left out in this suspension system in order to reduce weight (without reducing the comfort level). The flexible suspension system follows your every move, whatever your riding position. Mesh padding along the spine ensures a comfortable fit, even on challenging trails. The padding doesn’t absorb moisture and it creates a large ventilation channel to keep air circulating across one’s back.

Vent Active Bike

The Vent Active Bike suspension system offers stability and comfort on day trips or multi-day trips with a lightweight to medium load. An ergonomic back panel (EMP) ensures for even load distribution and high pack stability. Ventilation channels in the padding keep air circulating effectively.


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.

Ergo Shape

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.
