Technical Informations

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.
Backpack technical tests
The finished product is tested by simulating the treatment. Fabric, buckles, webbing, foam, zips, etc. Fabrics are tested for resistance to wear, tearing, colour-fastness in UV rays, washing, waterproofing, etc. A final test on the finished product simulates the kind of treatment to which it will be subjected over several years, to access the strength of the assembly. The backpack is weighted then placed on a dummy which then reproduces the movement of fast walking through thousands of cycles.
A score for comparing products' environmental impact
The product's environmental impact is calculated across its entire life cycle using different indicators. An overall ABCDE score is attributed to help you more readily identify the products with the best environmental performance by comparing the same type of product (T-shirts, trousers, backpacks, etc.) Decathlon is committed to visually displaying environmental information.

This is so handy
Used for 2 to 8 weeks
It is cheap and lightweight. I bought this for my 10 year old daughter to use at centre parcs for her swimming kit. It has been great and easily held everything she needed.. The straps were nice and wide at the top and therefore did not cut into her shoulders, easily adjustable and she had no problem cycling with it on.

This bag is so handy to use and take up no space. I use it when flying for my travel documents.
Great little bag
Used for 3 to 6 months
Compact enough to fit in the smallest handbag, or even put in my pocket when shopping, large enough to hold a small beach towel, suncream, sunglasses and my reading book. I never go anywhere without mine. I have also bought the same bag in various colours for many of my friends

Good compact bag, average build quality
Used for 2 to 8 weeks
Lovely and compact ideal for shopping and casual use but Alpenaz 10 very similar weight and pack ability and has a much better build quality. The ultra compact bag is better suited to light use rather than day hikes, after using it as a second small hiking rucksack while backpacking (and loving the fact it fit in my main bag) it started to wear at the seams - better shoulder straps would really help as with some weight in it the weakest point is where the straps join the bag at the shoulders. This could be avoided if the straps fabric was integrated into the back panel fabric avoiding the need for a seam. If wanting a slightly more durable bag I'd buy the Alpenaz 10 instead but both are good value for money and compact.
A compact, strong and light bag
Used for 2 to 8 weeks
I really like this bag. I cycle alot and space is a premium on a bike. This bag makes no difference to my weight load, easily stashed in my Jersey pocket. It seems strong enough and so far I've not had that feeling it will come apart at the seams when i put it on or take it off. Ive not stuffed it to the max but had a good load in it when I've accidentally bought myself presents on a whim. It also seems waterproof though not fully tested in a downpour, just a shower and the contents were all dry. Thumbs up from me.
Very good

Perfect for what I needed
My little bag
Used for 2 to 8 weeks
I bought this as a matter of convenience for my month long trip to Thailand. It's great... folds and scrunches into a tiny pocket and opens to a bar big enough to hold products I need for the beach/pool. I love it and great price too
