All our backpacks are tested in use by users who represent those for whom the products are designed, in conditions similar to those found in real-life. In particular, our "Test Missions" bring together the product manager with people who are not affiliated with QUECHUA, to test, develop and validate the products.
We test the bag's resistance to abrasion, tearing, colour-fastness with UV and washing and water-resistance both in the laboratory and in the field. Then a dummy reproduces the ageing of the weighted bag over years with fast walking movements, over thousands of cycles to check the resistance of the assemblies. The components (fabrics, buckles, straps, foam, zips ...) are also tested separately, allowing us to give these bags a 10 year guarantee.
Store your bag in a dry place.
