The components of the bag are water-repellent so that you can temporarily continue walking/hiking in light rain. Caution: this backpack is not watertight/waterproof and it does not have a rain cover. If you want to continue walking/hiking in the rain and protect your belongings, we recommend the following model: "20 to 40 L rain cover", which can be viewed on our website, item reference 8734213.

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.

- Loosen all the straps (straps, belts, load adjuster straps), - Put on the backpack, - Tighten the shoulder straps, - Adjust the load adjuster straps as needed.

- Put your heavy items at the bottom. Pack your clothes around these items; - Keep your waterproof jacket and/or fleece within easy reach; - Place small items for the day (sun cream, map, glasses, etc.) in the pockets. ; - The flask can be placed in the side pockets designed for this.

We carry out several laboratory tests to validate the bag's components: fabric, buckles, straps, foam, zips. For example, for a fabric, we test resistance to abrasion and tearing, colour fastness when subject to UV light and washing, 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.

Thanks to all your feedback, we have improved the design of our NH100 30-litre backpack. In this new model, we have added a compartment in the large pocket as well as a zipped pocket. We have also changed the opening to make the contents of your backpack more accessible.
