I was looking forward to testing this new MT900 UL. Bought the day before yesterday, first "analysis" the same day and first outing yesterday! No feedback yet on the resistance, but at first glance, it keeps its promises, even if two or three small things can still be improved to gain in comfort/solidity/weight: 1) Why have you placed the rain cover in the inside pocket of the flap? It would be better placed in a bottom pocket (which also protects and cushions the bottom of the bag when you put it down) 2) Why "knotted" rather than sewn closing straps? 3) The waist strap pockets are huge, almost disproportionate! 4) The string that acts as a compression strap: first, I find that it is less effective/strong than classic straps, then I feel that it will quickly annoy me to have this little piece of string that swings on each side... 5) The small straps that allow you to attach an element outside under the bag. In itself, a good practical idea. In reality, useless for those who do not have use for them (I hesitate to cut them). It would be better to provide attachment loops, either large enough to pass our own straps through, or with, for example, removable straps supplied as an accessory... 6) The small strap with a snap button that allows you to "secure" the closure at the top of the riser is of no interest! 7) In parallel with remark 5, and the biggest downside in my eyes, the double pull tab for the side opening: it is not at all secure in its lower part. With the result that it could open during a hike (snagging on a branch, bad joke or pickpocket in a public place, etc.). In addition, I have doubts about the waterproofness of this zipper (I am talking about the clasp in its lower part). That said, I salute the work of the designers who imagined this bag! My remarks are intended to be constructive and not critical ;-) Looking forward to the 2026 edition ;-)

Very comfortable backpack and very light for its capacity. The back of the backpack is made of mesh, so the back dries quickly when sweaty. Lots of possibilities for tying up equipment. Several practical pockets and a key hook. The backpack is unzipped almost along its entire length, which makes access to its contents much easier. Unfortunately, only in one color version. Others would be useful.

Used for a hitchhiking trip and everything is ok

Good capacity, practical and ergonomic, ok weight, small pockets and great hip support. Straps much too long and slight creaking due I think to the weight (no more than 12kg)

Comfortable and good support

very practical

The metal back frame presses on the shoulder blades when the bag is loaded. Despite all the adjustment tests, I preferred to part with this bag which hurt me. Too bad because it is also well designed for long-distance hiking.

great bag I use it on every long distance hike

Good, light backpack. Everything seems very well thought out. Not a real ultra-light product, but a good compromise between weight, comfort and durability at a fair price. Can be easily adjusted to my height (1.91).

Backpack, very light, comfortable to carry, some storage, perfect for long hikes.

Mountaineering bag is comfortable to carry and elegant in shape

very good quality and comfortable to wear when hiking, very happy
