I thought we had to spend more...

As quality is priceless, I shopped around for the big brands. But after hours of research and visiting quite a few stores, I came back to this very inexpensive Forclaz backpack. And I did well. I now hope it will last me 10 years like the previous Decathlon backpack.

Too small with a 3L water bag

Once the 3 liter water bag is positioned in the bag compartment, the space is reduced considerably. It is therefore necessary to anticipate the use of the water bag from the start. For my part it is becoming too small and I am going to return it.

Great backpack at this price

The backpack offers the same as backpacks from other brands at prices that are PLN 200-300 more. The carrying system is fantastic, with a fully loaded backpack there is practically no discomfort, and the mesh allows the structure to fit very well to the back surface while ensuring excellent ventilation. The only drawback is that the backpack is slightly rounded on the back side and you need to keep this in mind when packing flat items. However, this is compensated by a large number of side pockets or in the upper part of the backpack. I highly recommend the product

perfect backpack!

a great choice both for a one-day trip or for several days. Very cleverly designed, there is good access to many places without having to drag out all your stuff. I recommend!

I feel like I saw more options online after buying where there were more compartments for camera and the hook holding the tent is loose.

As with the MT900 UL line, the MT500 AIR range has a ventilated back structure with mesh fabric (net fabric) that helps the back to breathe and dries quickly. Rigidity is guaranteed by a reinforced frame. The back is adjustable with a release strap that’s easy and quick to use.

Recommended carry weight

According to the project for which this backpack was designed, we recommend you don’t load it above 15 kg. 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 to hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. The water bladder can be placed in the compartment provided down the back.

How to use the multi-use straps?

The new range of MT500 AIR and MT900 UL bags has two straps with open aluminium 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.
