Main fabric : 100.0% Polyester (PES)
All our backpacks are tested in the field by users who represent the target market under the same conditions as you would encounter in use. Our Field Test Missions team up our product managers with people not affiliated with QUECHUA to test, improve and validate our products.
We test the bag's resistance to abrasion, wear, its colour fastness under UV rays, after washing and its waterproofing in the laboratory and in the field. Then a mannequin is used to simulate the ageing of the backpack filled with weights over a number of years by reproducing fast walking actions, over thousands of cycles, to check the resistance of assemblies. The components (fabrics, buckles, straps, foam, zips... ) are also tested separately to guarantee these bags for 10 years.
Store your bag in a dry place.
