Why we developed ACTIVE SPINE 3.0

Carrying heavy gear in the mountains is demanding. Steep approaches, multi-day hikes, and scrambling over rough terrain often cause discomfort, fatigue, and reduced mobility. Traditional backpack systems can amplify these issues by restricting your body’s movement and forcing your muscles to work harder.

Our award-winning ACTIVE SPINE 3.0 distributes weight evenly, keeping your load centered for stability. Two pivoting points are connected by a lightweight glass fiber rod, allowing the hip belt and shoulder straps to mirror your natural walking motion. This third-generation design is lighter than ever, reducing strain so you can focus on the trail ahead.

We put ACTIVE SPINE 3.0 to the test

We studied ACTIVE SPINE and its effects on your performance at
the University of Applied Science Technikum Vienna. The results confirmed our hypothesis: compared to common carrying systems, ACTIVE SPINE 3.0 increases your range of motion by 14% in the hip area and 22% in the shoulder area.

Amazing, lightweight Pack!

"The Mammut Ducan Spine 50-60 is a pack I purchased for two reasons. First, I was looking for a pack that was well under 4 pounds. Second, I anticipated the independent spine system to help with my back issues when on backpacking trips. The Ducan Spine exceeded all of my expectations. It is a well constructed pack with a wire frame that allows for total independent movement. Where my hips go, my back isn’t going along for the ride. This has done wonders for my back. The pack is also sleek and simple, making my tired days easier. Storage is no issue with this bag— the main storage compartment can be broken up into two compartments. I store the “camp” stuff in the bottom and fill the top with my daily essentials. There are also a number of cool little gadgets on this bag, my favorite being the pack cover that’s stuffed in a small slit at the base of the pack. My hydration system fits like a glove as well! I couldn’t be happier with this pack. While most of my trips are short, I hope to complete 5-7 day trips this coming year. This bag would fit the bill for a weekend as well as a thru hike."

"Great pack for high adventure. Used on Trek, Philmont New Mexico (Scouting America) and served me very well. D Rossi T-167"

Gut aber fragil

"Sehr guter Wanderrucksack auch bei höheren Lasten und langen Touren. Leider sehr fragil. Zum einen arbeitet der Schultergurt das Material der Hüftgurte auf und Ösen reißen ein und zum anderen fallen Plastikkappen an den Gummizügen einfach ab."

— Elias G. (3/5)

Perfekter Rucksack für längere Wanderungen

"Der Rucksack ist sehr bequem zum tragen. Das Gewicht bei einem vollen Rucksack fühlt sich beim tragen nicht mehr als so schwer an."

Annoying squeak

"I bought this backpack for some multi day hikes in Patagonia. Now I noticed that the flexible joint causes an annoying squeak ever step I do. Don't buy this product. It may ruin your experience if you look fore a quiet time outdoors:-("

I brought too much stuff

"So I overpacked for the multi day hike that I'm on but thank god I bought this backpack. The back frame gives plenty of support. The quality of the bag itself is very good."

One bag to rule them all

"I took ages assessing almost every bag on the market available in the UK and stopped with this one. There were two/three issues with this bag but I'm so happy I took the plunge as they are significantly dwarfed by the pros. The issues? Lack of back length adjustment, weight (1.5kgs not a biggie) and non-removable waist belt. The pros? The 'spine' technology is simply amazing and unbelievably comfortable. The compression is superb in that with just day walking items it's slim and weighted extremely well, with a full expedition load it's got lots of access points and weights on hips/shoulders very very well. I would use this for 30-60l purpose. And again, the movement with the spine pivot is second to none...give the person a pay rise who thought of that! The material is light but strong and the shape is very well thought out with narrow at the bottom and wide(r) at the top."

Sweet Pack

"I just used this bag for the first time.. the spine technology is an absolute game changer with distributing the weight of the back and shifting as you move. Pack is super light and fits the body comfortably. The weight is a HUGE difference compared to regular packs. Everything fit well and it seems like it will durable for a while. After buying this pack I strictly want to purchase my outdoor gear from Mammut. Customer service was great, and the product exceeding my expectations. The one thing that bummed me out was when I pulled the thin draw string on the outside of the bag, the plastic piece ripped from the cords and made it harder to use. I had to tie a bunch of knots in it."

Highly Recommended

"Mammut Ducan 50-60 This is an excellent backpack, I couldn't be happier with it. I've just used it on a 9-day autonomous hike through the French Alps, carrying between 12-15kg. It is a tight fit if you want to carry tent, food, clothes etc but everything fitted in - great to have the added space due to the rolling top closure. You can believe what they say about the back system: yes it works! It leads weight very well to the hip belt, provides feedom of movement and excellent ventilation. I was a bit sceptical about the light padding of the hip belt, but I was wrong: it is very effective (I turned out to wear it bit lower than usual, more like a rather low-rise pair of jeans). I think it is true that the whole setup makes you less tired, because you don't have to move the mass of the pack along with the natural movement of your hips. Very comfortable indeed! It looks tight and clean and therefore rather pretty, even if the photos seem to show a weird sort of top-heavy bulkiness, which is certainly not the case in real life. Be aware that it is not really ultra-lightweight (still 1,5kg) but that regarding overall weight it performs well compared to traditional hiking backpacks. I'm curious about the durability of some fiddly bits (closing cords, light plastic hooks) but too early to tell. I got quite some interested questions and positive comments from other hikers, some even took pictures. So yes, I recommend you to check this one if you are looking for a state-of-the-art yet not ultralight backpack!"

Q&A

As the back size is not adjustable I'm wondering whether I should perhaps order the women's 50-60 as I'm 169cm tall. Any guidance would be gratefully received.: Hi Marc, it depends on your back length: the back length of the men's version is 48,5cm (L), the women's version is 43,5cm (S). - Barbara
Is this pack made for multi day trips? Is it rugged enough to withstand?: This pack is indeed rugged and would be ideal for multi day trips!
Bonjour, quel est le poids du sac à vide s'il vous plaît ? Merci d'avance.: Bonjour Nicolas, le poids est 1410 g. - Barbara
Bonjour, aucune info sur la charge maximale ? est il adapté à l'alpinisme et l'escalade ? cdt: Bonjour Anton, Ce sac à dos est destiné à la randonnée, pas à l'escalade. - Barbara
Is this pack good for a shorter person. 5.6 feet tall. I used a mammut pack in the past and had issues. And it does not mention anywhere that there is an adjustable back option: Hi Muhammad, Thanks for reaching out! Depending on the length of your trip I'd recommend a backpack that is somewhere between 40-60 litters. Both the Lithium Crest and Trion Spine are great adjustable packs for multi day trips. Lithium Crest: https://www.mammut.com/us/en/p/2530-03561-00087/lithium-crest/ Trion Spine: https://www.mammut.com/us/en/p/2520-00870-00087/trion-spine-50/ While not all of our packs have adjustable backs, both the Lithium Crest(46/48.5/51/53.5 cm) and Trion Spine(46/48.5/51 cm) have adjustable back lengths that can be found under the features section. Please don't hesitate to reach out if you have any other questions regarding our products.
