All our backpacks are tested in the field by users who represent the target market under conditions identical to those found in typical use. Our Field Test Missions team up our product managers with people not affiliated with QUECHUA to test, improve, and validate our products.
store your backpack in a dry place.
To ensure materials retain their properties (especially waterproofing), we recommend you to not machine wash, tumble dry, dry clean, or bleach your backpack. Do not iron. To clean your backpack by hand, use warm soapy water and a brush if needed. After a few years of use, you should renew the water-repellent properties of the fabric by using a waterproofing spray.
