How to Choose the Right Hiking Backpack? A Guide to the Technologies of Mammut, Deuter, Bergans, and Millet

Choosing the right backpack is crucial for any mountain adventure. Whether you’re preparing for a short day hike, a multi-day ridge traverse, or technical climbing, the right backpack will provide not only comfort but also the necessary functionality and safety. To make your decision easier, we’ve prepared an overview of four leading backpack manufacturers—Mammut, Deuter, Bergans, and Millet. We’ll explore their innovative technologies and what makes their backpacks stand out.


Mammut: Swiss Precision and Innovations for Maximum Freedom of Movement

The Swiss brand Mammut has been synonymous with quality and safety since 1862. Their backpacks are designed with a focus on detail, durability, and maximum comfort when moving in challenging terrain.

Patented Technologies and Innovations:

  • Active Spine Technology™: This breakthrough back system technology allows the upper part of the backpack and the hip belt to move independently of each other. This mimics the natural movement of the spine during walking, evenly distributes weight, and provides unparalleled freedom of movement for the shoulders and hips. The result is less fatigue and greater comfort, especially on long and steep ascents.
  • Removable Airbag System 3.0: For those navigating avalanche-prone terrain, Mammut offers one of the lightest and most compact avalanche airbag systems on the market. This system can be easily removed and used in multiple compatible backpacks, enhancing their versatility.
  • Highly Durable and Sustainable Materials: Mammut emphasizes sustainability. Many of their backpacks are made from recycled materials with a PFC-free water-repellent treatment, which is environmentally friendly.

Why Choose Mammut?

If you’re looking for a backpack that allows maximum freedom of movement, is technologically advanced, and prioritizes safety and sustainability, Mammut is the ideal choice. Their backpacks are like Swiss watches—precise, reliable, and innovative. They’re perfect for dynamic movement in the mountains, from hiking to alpinism.

Deuter: German Durability and Legendary Back Systems

With over 120 years of history, Deuter is one of the oldest and most respected backpack manufacturers in the world. The German brand is renowned for its uncompromising quality, durability, and, above all, legendary back systems that have set the standard for comfort.

Patented Technologies and Innovations:

  • Aircomfort System: A revolutionary back ventilation system patented by Deuter in 1984. A flexible steel frame and special mesh create a space between the back and the backpack, allowing air to circulate freely. This reduces perspiration by up to 25%, significantly increasing comfort during hot days and demanding activities.
  • Aircontact System: Designed for heavier loads and longer treks, the Aircontact system features special open-pore foam and ventilation channels that create a “pumping effect” with every movement, ensuring air circulation. The backpack sits firmly and securely on the back while remaining well-ventilated.
  • Vari-Flex System: A movable hip belt that follows your body’s movements. This allows for better balance and less fatigue, as the backpack adapts to your movements without restricting you.
  • SL Fit (Slim Line): Deuter was one of the first manufacturers to focus on the anatomy of the female body. SL models feature a shorter back, narrower shoulder straps, and a conically shaped hip belt for a perfect fit to the female figure.

Why Choose Deuter?

Deuter is a safe bet. If your priority is maximum carrying comfort, excellent ventilation, and a backpack that will last for years, you’ll definitely find something in Deuter’s range. Their attention to detail, ergonomics, and segmentation (backpacks for women, for tall people) make them a favorite among a wide range of outdoor enthusiasts.

Bergans of Norway: A Norwegian Pioneer with a Focus on Lightness and Sustainability

Bergans holds a special place in the outdoor world—Ole F. Bergan patented the first backpack with an external frame, as we know it today, in 1908. This Norwegian brand remains true to its heritage, focusing on functionality, low weight, and sustainable solutions.

Patented Technologies and Innovations:

  • QuickAdjust™ PRO and SPINE II Carrying System: These modern back systems allow for easy and precise adjustment of the back length, ensuring the backpack fits perfectly to any body shape. The SPINE II system also provides excellent flexibility and support while maintaining low weight.
  • Bergans FlowPanel: Ensures optimal ventilation and moisture wicking from the back, enhancing comfort during long hikes.
  • Safeback SBX: In its latest models, Bergans introduces an innovative avalanche system that is not an airbag but an air supply system. In case of burial, it can pump fresh air from the snow into the breathing area, extending survival time.
  • Sustainability and Durability: Bergans is known for using durable materials like Cordura® and a strong focus on sustainability. Many of their products are made from recycled materials, have bluesign® certification, and are PFC-free.

Why Choose Bergans?

If you’re looking for a technically advanced, lightweight, and extremely durable backpack with a story, Bergans is made for you. The Norwegian design school is reflected in a minimalist yet highly functional design. It’s the choice for those who value history, innovation, and a responsible approach to nature.
