The best backpack of my life. Ultra light, the weight saving is incredible and very appreciable when you start to get older in mountain hikes.

Bag bought for a road trip in Europe Perfect, practical with its side and top opening and the adjustable straps for the back or pockets / pouches. The inserts on the sides are a real plus for large capacity water bottles. I recommend!

Really very light Trek bag, the different bags allow you to store everything you need to leave with peace of mind. Good distribution of the load between the shoulders and the pelvis, real carrying comfort and a real plus over the distance. Used every day on 20km sections.

Hello. I have been hiking in the mountains with this bag for a little over a year now. Overall I am delighted with it! The positives: Rather light Not too expensive Pretty You can customize it a little to save weight and erase some flaws. Practical multi-adjustments of the straps and carrying straps effective and simple! The two pockets on the waist belt are very practical! Solid! Practical and solid zipper on the length of the bag, possibility of opening it from the bottom. The negatives: Most of the straps are too long (I cut them, a formality, small weight gain) The side pockets are poorly designed, impossible to access them properly while walking, side string system really not great, you risk losing the contents while walking! (I also customized and closed these pockets using the original strings, no more risk of losing their contents) Central back pocket a little small but I'm nitpicking... I removed the removable pocket on top, useless for me, also useless the cover-rain that I replaced with a Nylofume waterproof bag (200gr saved!) The straps are not super comfortable but you end up getting used to it, I rarely exceed 12kg of load. The bag does not stand up, I find that a shame... Despite its small flaws and if I had to do it again I would take the same one, I recommend it to you!

Great backpack, carrying comfort is good but you should not load it too heavy (= +15kg). Although not ultralight, you do have a ventilating carrying frame with mesh. I cannot yet make any statements about whether this backpack will remain intact, 3 months of use is too short for that. Handy zip pockets on the hip belt for small items. It takes some getting used to packing because the main compartment is 1 whole without compartments, it is handy that the zip runs over the entire height of the backpack, so that you can reach everything without having to empty it. In my opinion, the side pockets could have been closed. All in all, I am quite satisfied with it. Top price-quality ratio.

By FAR the best backpack I've ever had. It's not the lightest on the market, but it makes up for it with the abundance of compartments and attention to detail that no other UL backpack has. Absolutely perfect, I would just like to know why they didn't include the usual elastics at the top because it's not particularly expensive and I'd rather have to remove them than add them, but that's it, it doesn't take anything away from the backpack.

The bag is great. Well designed. Lots of pockets, very practical, especially those on the side that are accessible while walking. As for the squeaks implied by some comments. When the straps are adjusted properly, you can no longer hear this noise.

Super practical with opening all over the bag. Very comfortable on the back. Light. I don't regret it.

I bought the MT900 UL bag to do the tour of Mont Blanc over 6 days, I am more than satisfied!

***** PERFECT *****

I am enthusiastic about this backpack that I have been using on the GR 34 for 10 days now, it is good in every way, I have seen some comments saying that the straps were too long, that the pockets were not practical, this and that, the gloomy minds should calm down because it is great value for money and I know what I am talking about, I had another Osprey atmos 65 bag at €250, which was no better except perhaps for the carrying comfort but at 2.5 kg instead of 1.3 kg. So bravo to the designers.

The backpack looks well made. It is relatively light and pleasant on the back. Pockets and various compartments for drinks, etc.. are well thought out and practical. I haven't used enough to be able to evaluate the durability, but I believe it will be good :)
