Great backpacking pack

Decathlon have nailed it with this pack. After 2 seperate multi day backpacking hikes I love the way it is designed. The internal layout with multi straps makes it easy to remove your sleeping bag etc without all your clothes collapsing, the pockets are all easy to access even with cinch straps tightened, there are loads of accessory loops for attaching quick grab items to the outside and I really love the bottle holsters. What a great feature these are for sweaty treks. 50+10 is a perfect size for summer backpacking where you don’t need to be carrying bulky sleeping bags and clothes. Strongly recommend this pack.

It was much better than expected

I was not aware it was a Mens trekking pack! Once adjusted for my height 1.65 mt , it was very very comfortable. Was easy to use , many compartments and so easy to access.

Very product with some room for improvement

As usual with Decathlon, the product is at least as good as name brand products but significantly cheaper. It's a good size for solo mutli day hikes with compact kit. The straps and back are comfortable. The front opening to the main compartment is handy, as are the compression straps. I've got no regrets whatsover, especially at this price. However, there's a couple of areas that could be improved for future iterations: The waterproof cover pocket is on the inside of the 'hood' of the rucksack. This a puzzling design choice, as when it rains and you want to use the cover, you have to open your rucksack to get it out. It would be preferable if this was accessed from the outside of the bag. A zipped pocked on the front of the bag would be useful. The side zidded pockets are compessed between the main bag and anything in the elasticated pockets, so aren't much use for snacks etc. The water bottle holder pockets could do with being wider. It was awkward for me to fit the 500 Tritan 1.2 L flask into these. However they work well for other bottles.

Worth every dollar for this pack

I have a number of larger 60+10 / 70+10 backpacks from other leading brands for years and this year for the family camping trip I started to get a smaller one. Although this 50+10 version is the smallest among the collection, but the sturdy body makes the room very usable. The pockets and the water bottle holder are very thoughtful too. First trip loaded including bag weight 24kg and very comfortable and well balanced on uneven paths.

Best Value

For the price this backpack is the best, all the features needed for hiking are available, including features that must be in a modern backpack. To get everything in this backpack usually more money is spent. I really like it and will probably use it for a long time

High Durability

I’ve been using this bag from last 2 or 3 years, this Bag never disappointed me. Best quality.

It’s good

It needs to be lighter,way lighter.The bag on its own is heavy with the metal strip to hold its shape. instead all u needed is a thin light rod like i have for my Wildcraft bag. If u need to be carrying ur sleeping bag,mattress,and clothes and food,it will become tooooo heavy. i dont think i will be using it. though i loved the straps holding the stuff inside.And the shape of the water bottle pocket

Great Bag

Just Go for it.

The product was expected to be really good and yes the design is excellent however the workmanship on the product is really very poor , with all stitches visible and very poor assembled also the product looks gorgeous from far but when you actually have a closer look the Aluminium reinforcement seems to be bubbled up with lots of dents on portions of it ... ! Also the feel of the material is very good but fades overtime with heat and water stains it up during long trails ...!!! Also damb feeling was felt on the inside of baggae when the product was opened up and no desiccant was used to preserve the product...!! Totally unexpected from Decatlon Brands like Forclaz ..!


Thank you for taking the time to give your valuable review. We are sorry that you were not satisfied with the product. Please visit your nearest Decathlon store to get the product physically checked so that we can provide you with the best possible solution.

The balls are then emptied into a graduated container in order to determine the equivalent volume in liters, with a margin of error of just a few %

How to pack a backpack?

Put your bedding at the bottom. Place heavy equipment near your back (tent, stove, food). Pack your clothes around these items. Your sleeping mat can be placed under the flap and the tent under the bag if there is no room inside. Keep a waterproof jacket and fleece to hand. In the pockets, place small items for the day (sunscreen, map, glasses...). The water bag should be placed in the compartment that is usually placed the length of the back.

Why are our rain covers gray when some trekkers want them to be brightly colored?

The gray color used for the covers of our backpacking rucksacks is neutral because it consumes less dye. The component is made of BITON: this process allows us to lower our CO2 impact and reduce consumption and water pollution in comparison to colored models. These small measures demonstrate the commitment of Forclaz to improve the environmental impact of its products.

Symbium technology

In order to be comfortable, a backpack must also be well-balanced while you walk. Symbium technology consists of a jointed waistband that allows the backpack to adapt to the backpacker's movements when walking. Thanks to the symbium system you can say goodbye to the swinging effect that tire out trekkers.

10-year warranty

Our engineers have conducted tests simulating the aging of rucksacks. These tests are conducted on the components, seams and finished product. The results enable Forclaz to guarantee the tested bags for 10 years from the purchase date shown on the receipt



Product testing

All our backpacking rucksacks are tested in use by users who represent those for whom the products are designed, in conditions similar to those found in real-life. In particular, our "Test Missions" bring together the product manager with people who are not affiliated with DECATHLON to test, improve and validate the products. This specific model was approved by trekkers on the Tour du Mont Blanc route.

Storage instructions

Store your bag in a dry, ventilated place away from direct light.
