Used mainly for hiking/bivouac with photo equipment, very comfortable with more than 15 kilos on the back, perhaps an improvement on the side pockets to be reviewed, I find that they are not easy enough to access, the central opening is a big plus, you don't have to empty the bag to get your personal belongings from the bottom

Great for a bacpacking trip!

Bought this backpack for a 2 month backpacking trip around South East Asia and had no issues with it. Recommend for those who plan to travel relatively light as the main compartment is not overly massive.


Everything fits in there and for a scout it's perfect

Very practical bag for hiking.

Fragile fabrics!!!

Hello, First use during a 3-day outing, I greatly appreciated the functionality of this bag through its really well thought-out compartmentalisation. All of its straps facilitate adjustments during carrying. The pockets at the waistband are really a plus for small cravings. However apart from all these good points, a big downside, the quality of the interior and exterior fabrics, because I regret that after an outing, I find myself in possession of a pierced fabric inside the bag itself (water pocket separation)! In addition, the material of this backpack marks really easily (friction, scratches, etc.) Too bad the quality is not there for a product that deserves better...

Good product

A marvel, quite simply!

This backpack is a concentrate of know-how very suitable for itinerant hikes. Light weight compared to the volume (1790g), Comfortable fit, Extensibility, Side closures, Fineness of the straps and closures, Large number of pockets: side, bottom, top, inside... both integrated and separable, Interior straps to adjust the volume and reduce the pressure on the external fabric, Chest strap easy to handle (with one hand), Integrated whistle, And maybe I forgot other useful details and pleasant. The only flaw in my opinion is that it does not stay upright. He always needs support. I did a 15 day trek with the bag. Very pleasant !

Seems very light thanks to its many settings

After several mountain hikes including 2 bivouacs, this bag is great thanks to its multiple settings, the straps are very very long, I'm going to cut them because in knot mode it hinders movement, the clips are indeed small with gloves, I doubt they will Accessibility, but less plastic is better... back ventilation is good, honestly I'm happy with my investment I hope it will last but I trust the brand (V)

Recommended carry weight

According to the project for which this backpack was designed, we recommend you don’t load it above 33 lbs. Then you can benefit from all its features. Moreover, it’s not recommended to carry a load greater than 20-25% of your own weight and put too much pressure on your back.

How to pack a backpack

Put your bedding at the bottom. Put heavy gear (tent, camp stove, food) near your back. Store your clothing around it. A groundsheet or tent can be placed under the flap or under the bag if there isn't room inside. Keep your waterproof jacket and fleece at hand. Place small items for daily use (sunblock, map, glasses, etc.) in the pockets. The water bladder can be placed in the compartment provided down the back.

How to use the multiuse straps

The new range of MT500 Air and MT900 UL bags has 2 straps with open aluminum buckles (on the lower part of the bag). These straps let you hook on a tent or mattress under the bag or on the barrel. If not in use, these straps can be stored (by pushing them inside) in the hidden pocket intended for this or detached and used elsewhere with the lark's head knot buckle.
