Hello Ella, Thanks for your review, we are so glad to hear you're enjoying this backpack!

Perfect compromise between functionality and size

I used this bag for half day/full day hikes and it is just the right size/weight. Lot of pockets inside outside. Comfortable and light. Very good idea the cool box compartment. The bag looks wear and tear resistant, time will say. I am missing an additional "belly strap" to avoid the bag to bounce when going down faster. To make it right a very good "day back pack" !

poorest quality zips. came apart in just one week.

What a waste of money. All the zips(read all) ripped apart and broke so easily like tearing a paper. Not expected this from decathlon. Lost my camera equipment as the zip tore apart by itself during a hike. Do not buy this product. It just looks good but doesn’t perform well.

It’s not worth the amount

In 2500 inr a very different is expected from decathlon .

How is volume measured?

The volume of each backpack is measured using a standard 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, belt, load adjuster straps)2 - Put on the backpack3 - Tighten the shoulder straps4 - Adjust the load adjuster straps as needed

How to fill your backpack?

Put your heavy items at the bottom. Pack your clothes around these items. Keep your waterproof jacket and/or fleece within arm’s reach. Place small items for daily use (sun cream, map, glasses, etc.) in the pockets. The water bladder will be placed in the compartment provided along the back, and the water bottle in the outer flask holder pockets provided for this purpose.

Developed thanks to your feedback, tested with hikers

This bag was designed thanks to all the customer feedback and hikers' observations.Indeed, the idea is to separate and keep your picnic cool when hiking, while separating it from other belongings (clothing, wallet, telephone, etc.).This bag has been tested by many hikers and has enabled us to test its functions and make some improvements.

Tested for optimum durability and strength

We carry out several laboratory tests to validate the bag's components: fabric, buckles, straps, foam, zips. For example, for a fabric, we test the resistance to abrasion and tearing, colour fastness when exposed to UV light and washing, and waterproofing. We also conduct tests to check the resistance of assembly using a dummy that reproduces the movements of a hiker to replicate several years of wear and tear on the bag.

We have reduced our environmental impact on this product

Dyeing textiles requires a lot of water and discharges wastewater into the environment.To reduce this impact, we use the following two dyeing processes:1. We don't colour the interior fabric.2. We use mass pigmentation adding the colour pigments when the yarn is produced for the dark grey outer fabric.This is still not enough and we are working to make this product eco-designed
