Product Customer Reviews

This is an outstanding bag for the price, it looks great, very comfortable on long hauls 30+ miles 40lbs average loadout in the North Carolina mountains. The material is very durable canvas and the buckles are sturdy. It’s not the lightest bag out there and could use some extra pockets which isn’t a big deal for me personally.
The best comfort and space equation out there. Lots of room to carry what i need, as comfortable as possible. And so durable I know it will serve me for a long time.
Managed to fit all my gear for a 3 night hike as well as my gm1000 gold detector. Very comfortable with lots of access points to different parts of the pack
My son and I are going to use these packs for our backcountry camping adventure. Comparable packs from other brands range from $250 and higher. This pack is well designed and very comfortable to wear. Currently in my pack I have a 6 lb tent an inflatable sleep pad, a 10F sleeping bag and an inflatable pillow. I also have my cookset with fuel and chair along with a rain coat and a bubble jacket. After packing I still have plenty of room for other smaller essentials. The hip strap and adjustable back also distribute the weight very comfortably.. I feel very confident in this pack, our first hike is 2 hours long to get to the camp and I am sure I will be comfortable in this.
Hello Erik,

Durable and water proof material. Robust clips and elastic cord. Well thought out design. Can outer attach hiking poles and rock hammer. Excellent water bottle/flask pockets. Spacious belt pockets (can hold a mobile phone). Enough compartments to organise dry, wet or dirty gear. Can top load but also access main cavity by front J zip. Fully adustable system so very comfortable whilst carrying 15kg. Volume allows easy carriage of 3 season gear. Wife says it looks good on my 175cm 75kg frame and she can easily access items via the J zip so she also gives 5 stars.
This is the best by far all round backpack out there, it's a really competitive price high quality materials. The strap adjustable system is unquestionably one of the best out there.. This product has made me question myself, I've ignored Decathlon own brand name product for a while.. But no more, I'm a massive fan now..
So light ang huge

Easyfit system
Our patented Easyfit system allows you to adjust the height of the back and tightness of straps at the same time by pulling on a single strap (on each side).1. Put on your bag2. Fasten and tighten the belt3. Pull the straps (upward)And you're done!
How to pack a backpack
Put your bedding at the bottom. Place the heavy equipment (tent, stove, food) near to your back. Pack your clothes around these items. A ground sheet or tent can be placed under the flap or under the bag (add straps) if they don't fit inside. Keep a waterproof jacket and fleece at hand. Place the small items that you will need during the day (sunscreen, map, glasses, etc) in the pockets. The water bladder can be placed in the compartment generally provided down the back.
Why are our rain covers gray when some trekkers want them to be brightly colored?
The gray color is neutral and therefore uses less dye. The component is made of BITON: this process allows us to lower our carbon footprint and reduce the consumption and water pollution in comparison to the colored models.These small measures demonstrate the commitment of Forclaz to improve the environmental impact of its products.
10-year warranty
Our engineers have conducted tests simulating the aging of backpacks. These tests are conducted on the components, seams and finished product. Forclaz use the results to guarantee the tested bags for a period of 10 years, starting from the date of purchase indicated on the receipt
Product testing
All our backpacks are tested in use in the field by target users under the same conditions as they would experience in real-life use. 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 particular model was tested over a 5-week period by trekkers in the Canaries, Pyrenees and the Mont-Blanc mountain range.
Storage instructions
Store your bag in a dry, ventilated place away from direct light.
