    Major flaw part 2

    I totally agree with Jonathan's comment. I have the old version of this and it's excellent and very comfy. I thought the review about the 4 straps might have been a personal comment but I was wrong. Went to buy one today and I totally agree the 4 side straps just dig into the lower back. I cannot believe this rucksack got into production unless there is a faulty batch? I think the quality of this product looks good but major flaw in the lower back strap design. I hope the new design fixes this problem as the previous version is great and still going strong. This was for my wife.

    Brand's answer :

    Hi Neil,

    Thank you for your feedback. The reason that the hip belt has four straps which attach to the backpack (rather than just two larger straps) is to provide space for ventilation. However, if you feel this design results in an uncomfortable fit we will pass this information onto the brand as the bag is being re-designed for summer 2018.

    If you remain dissatisfied with the backpack you may still exchange it at any of our stores. If you purchased the product on our website you can return it by post by following the instructions on the webpage:

    Major Flaw

    I would have to agree with other reviews here. This looks like an excellent bag and there are so many great features on it but it has one immense and deal-breaking flaw. On the waist belt there are four textile bands (two on each side) that connect the waist belt to lower back pack. These bands run towards the centre of the bag, meaning that if you put any weight in the bag then these 4 bands act as massive pressure points on the lumbar region of your back. The bag weight is not distributed evenly across your lower back and you will end up with four red marks on your back where the bag’s weight is being transmitted through these bands. This is what happened to me.

    It blows my mind how any company would design a hiking bag like this. They have clearly gone for aesthetics over functionality. If you look at similar bags like the Berghaus Freeflow you will notice there are no lumbar pressure points on the bag.

    If you are just using it for very light stuff where not much weight will be transmitted to your lower back then you will likely not have a problem.

    Great features let down by poor fit

    Packed full of features for such a great price however the rigid frame is poorly designed resulting in it pressing into the shoulder blades when loaded with walking or hiking gear. There is no padding between your back and the frame. It may fit you perfectly but I'd suggest loading it at home with your hydration bladder and kit to see how it feels. Really wanted to love this bag.

    Brand's answer :

    Thanks for your feedback on the Forclaz 20 Air backpack. I apologise for the inconvenience caused by the comfort of the backpack’s frame, I shall pass your feedback onto the product manager. The product will be reengineering for summer 2018 which alters the shape of the metal frame slightly. If you remain dissatisfied with the backpack you may still exchange it at any of our stores if purchased within the last 365 days.

Laboratory Testing
We carry out laboratory tests to validate all component parts: fabric, buckles, straps, foam and zips. For example, for fabric: resistance to wear, tearing, colour-fastness under UV rays, washing, waterproofing. A final test on the finished product simulates the kind of treatment to which it will be subjected over several years, to assess the strength of the assembly: the backpack is weighted then placed on a dummy which then reproduces the movement of fast walking over thousands of cycles.
10-year guarantee, technical partnership
The heavy stitching research and development department, Quechua's partner for researching and testing its components and assemblies, conducted tests simulating backpack ageing. The tests focused on components, seams and the end product. As a result of these tests, Quechua can guarantee all bags tested for a duration of 10 years from the date of purchase indicated on the sales receipt.
10-year guarantee, conditions
The guarantee covers any backpack faults, except those caused by normal wear and tear and improper use. This special 10-year guarantee will only be granted upon presentation of the product and sales receipt. If the product is covered by the warranted, it will be repaired or exchanged for free. This commercial guarantee does not affect any statutory guarantees that are applicable in the country of purchase.
How is backpack volume measured?
The volume of each backpack is measured using a standardised method: we fill the main compartment as well as each pocket with little balls. Then we empty these balls into a graduated container, which gives the equivalent volume in litres.
How to adjust your backpack?
1 - Loosen all the straps (straps, hip belt, load adjuster straps). 2 - Put the backpack on. 3 - For backpacks with a capacity of 50 L or more, place the hip belt correctly (it should sit over the pelvis) and tighten it. For smaller backpacks, the belt should be placed around the waist. 4 -Tighten the shoulder straps. 5 - Adjust the load adjuster straps as needed.
How to pack a backpack?
Put your bedding at the bottom. Place heavy gear (tent, camp stove, food) near your back. Pack your clothes around these items. The groundsheet should be placed under the flap and the tent beneath the pack if there is no space inside. Keep your waterproof jacket and/or fleece close to hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. Put the water bladder in the compartment that is usually provided
Environmental measures
Oxylane and Quechua have chosen to inform you of the environmental impact of its hiking backpack products over the entire life cycle. This work follows an experiment completed in July 2011 with the French Ministry of Ecology. Scores ranging from A to E were awarded based on comparisons between Quechua's backpacks only. Details on this project and the calculation methods used are available at
