Incredible and very roomy bag

This is my first hiking bag and I think it's amazing! Huge, very roomy with countless pockets inside, on the top and sides. Compartment for a water bag, removable waterproof protective cover which completely covers the bag. Pretty color, slightly grayed blue, although I would have preferred a more natural color. The price is justified by the quality of the bag, plus the brand is very committed to the environment.

Not at all comfortable

I have never had so much pain in my lower back with a backpack. I limit myself to moving with it, it makes me suffer too much even though it weighs 7,800 kg.

so awesome

comfortable, adjustable, with a removable bag for visits or shopping..." while taking the minimum. Its numerous pockets, the adjustable and adjustable straps on the shoulders taking into account the chest... this bag is TOP. I am conquered

Comfortable women's backpack

Beautiful design. Sits easily on the back and shoulders. Plenty of storage space for your clothes and travel necessities.

I recommend

Ergonomic, comfortable, practical waterproof cover, hook fabric front for easily attaching carabiners, weighs a certain weight even empty with the frames but not the same feeling of heaviness once on the back for a long journey on foot

Top! very comfortable and practical, a little long can sometimes bother the head/neck if it is incorrectly adjusted!

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 : 69cm, Width: 43cm, Depth: 35 cm


Extendable volume: 50 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.

Symbium technology

The Symbium concept reduces the swinging effects which tire the trekker. This concept is based on the optimisation of the structure of the belt, ensuring that the backpack is better balanced when walking.

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...)

Timeless styling

We have selected pigment colours and used clean lines for a timeless style that will be passed down from generation to generation.

Complementary accessories

Compatible with 2x7L 1/2 moon storage bags.It's important that you are well equipped for your trek to take place in the best conditions. So to complete your equipment and make your MT100 backpack easy to use, check out our storage accessories

Female body shape

Our women's models are adapted to the female shape (chest and hips). The shoulder straps are more open and the waist fitted higher for greater comfort and freedom of movement.

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.
