TECHNICAL INFORMATION Reducing environmental impact: Dyeing fabrics requires a lot of water and a lot of wastewater is discharged. To reduce this environmental impact - we apply 2 dyeing processes to the product: - We do not dye the threads of the inner fabric - - We apply the dyeing process in large pieces and apply the colors in the production process of the thread on the black-dark blue and blue/turquoise outer fabrics - references: 8529024- 8583151 and 8731516. How to measure the volume of bags? : The volume of all backpacks is measured using a standard method: We fill the main compartment and all compartments of the bag with small balls. We then pour these balls into a container with a scale that shows the equivalent volume in liters. How should I arrange my bag? : - First of all, loosen all the straps (suspenders, belts and tensioners). - Attach the bag - Tighten the shoulder straps - Finally - adjust the tension straps to suit you. How should I place my bag? : - Place your heavy items at the bottom. Place clothing around these items - Put your raincoat and/or fleece within easy reach - Small daily items can be carried in the eyes (sunscreen - map - goggles...). - The water bottle should be placed vertically in its special compartment on the back. Flasks should be placed in the flask compartments on the sides of the bag. It has passed lifespan and durability tests: Many laboratory tests are applied before the components used are approved: fabric-buckle-strap-foam-zipper tests. For example, we carry out tests for fabric: resistance to wear and tear - color protection against UV rays and washing, and water resistance. We then subject the bag to years of accelerated wear testing on a dummy that mimics the movements of a hiker to measure the quality of assembly. Your feedback is important to us! : Thanks to your feedback, we improved the design and model of the 20L volume NH100 backpack. In this new model - we changed the main zipper to make it easier to open. We also added a zippered pocket and a compartment to the main pocket.
