Very elegant and nicely designed. Makes it easy to take out clothes horizontally and also put in last minute items vertically. Smart design.

Heavy Champ

Carried 65 pounds over several days with no problem. The thick shoulder padding helps a lot. More of a winter backpack.

Brilliant. Comfortable and made to last.

Have used this for a couple of month long mountaineering courses, and a few expeditions in testing conditions carrying about 25Kg and it’s an understatement to say that this backpack came through. The shoulder adjustment options for one’s height, water bottle pouch, and the two front zippers in addition to the small pouches on the waist strap are very well thought of and the material is super durable. This review is coming after three years of purchase and I still cannot find a thing wrong with this product to pick on. My only peeve with this is that the clip with whistle on the chest strap broke and there’s no way to get it repaired/replaced. It’s a bit inconvenient to use this fully loaded in expeditions without a functional chest strap as the shoulder straps can keep moving away. Would be great if the folks at decathlon also provided service options for a product that’s excellent otherwise.

Ideal companion

Offered for a world tour, it proves very effective on a daily basis. A more solid cover would be a plus

I purchased this bag about a year ago and I have only used it a few times. Despite it being extremely heavy at 6 lbs or almost 3 kilos, I purchased it as my largest pack that would be able to carry a lot of weight comfortably. Boy was I wrong. The only thing I wanted to use this pack for was carrying a sht ton of weight. It seems to be built just for that right? extremely heavy with a super rigit frame and tons of expansion options. Well I am sad to say that carrying over 40lbs with this pack just is not comfortable at all. In fact, the pack can handle maybe 30 pounds!!! Anything more than that and it does not feel comfortable. What a shame, I was planning on carrying upwords of 50 pounds for small distance snow camping trips. I am pretty dissapointed.

Very good value for money bag

Great value for money for those looking for a sturdy bag with volume. Small downside for the weight but that's normal for this price.

Very good bag of…

Very good mountain bag. Super practical and relatively light for its size and especially its capacity. Lots of accessible pockets and with good closures. Washing is sometimes a little delicate but once you get the hang of it everything is fine.

Additional Product Information


Main fabric: 100.0% Polyester ; Lining: 100.0% Polyester ; Yoke: 100.0% Polyamide ; Webbing: 100.0% Polypropylene ; Bag cover: 100.0% Polyester ; Coating: 100.0% Polyurethane


Height : 77cm, Width: 48cm, Depth: 38 cm


Extendable volume: 70 L + 10 L extension thanks to the bag’s top flap with adjustable height. The volume of each backpack is measured using a standardised method. we use small balls to fill the main compartment as well as each pocket. The balls are then emptied into a graduated container in order to determine the equivalent volume in litres, with a margin of error of just a few %.

Bag construction

The assembly of the different parts of this bag has been proven to withstand high tension levels, especially when it is filled or handled.Each element has been designed to guarantee the reliability of the construction: thick front zip (10mm), reinforced seams at the base of the skirt and on the straps.

How to pack a backpack?

Place your sleeping equipment at the bottom of your backpack. Position your water bag in the compartment provided for this purpose. In the back, place the heavy equipment (tent, stove, food) and position your clothes around it. Your tent or groundsheet can also be placed under the flap or under the bag. Keep your waterproof jacket and warm layer within arm’s reach. Place small items for daily use (sun cream, map, glasses etc.) in the pockets...)

Complementary accessories

Compatible with 15L half-moon storage bags.

Product testing

Several laboratory tests have been carried out to test the resistance of the MT900 Symbium backpack. We have therefore undertaken: a Martindale test which evaluates the abrasion resistance of this backpack, an initiated tear test (seams), a fatigue test on the compression of the foams, a test of resistance to rigidity and bending of the aluminium structure (located at the back of the bag).

Storage instructions

Store your bag in a dry and ventilated place, out of the sun.
