The American company Osprey focuses exclusively on the production of backpacks, which is strongly reflected in their high quality, design and technical details and improvements (e.g. Custom Molding System - heat moldable waist belt). In the OSPREY range you will find backpacks designed for several days of demanding treks in the wilderness, as well as a perfectly refined series of backpacks for cycling and for rock climbing fans, and it does not forget about small travellers with a range of technical children's backpacks. Osprey backpacks have won awards from prestigious outdoor magazines such as Backpacker Magazine, Outside Magazine.
The Mighty Guarantee warranty guarantees lifetime service for a damaged backpack even after its standard two-year warranty. If you need help with the Mighty Guarantee warranty, please do not hesitate to contact us.
If you discover any defect on your backpack, we will always try to repair or replace it free of charge (within its reasonable lifetime). In cases of wear and tear or accidental damage, we will then try to repair it for a reasonable price. As part of our efforts to protect the environment, we try, whenever possible, to repair products rather than replace them.
Below are some examples of what type of damage is eligible under the warranty.
|
Fabric If we find that the fabric was damaged during manufacturing, then this is something we could repair free of charge. Fabric that is torn or pulled out of a seam will not be handled free of charge; however, we will be able to help with the repair. |
 |
|
Zips Zips are constructed with a continuous row of teeth that is sewn to a length of material and then inserted into the backpack. Accidental damage and issues resulting from poor maintenance of these zips are not covered by the warranty, but can be repaired. |
 |
|
Stitching All our backpacks are built to the highest standards. Stitching faults are covered by the warranty. If stitches have been cut or pulled out by excessive force, they cannot be repaired free of charge under the warranty, but they can be repaired for a reasonable price.
|
 |
Cases in which the All Mighty Guarantee does not apply:
- 1. Choosing the wrong size
- 2. Personal preference – an unsuitable colour, model or size cannot be claimed
- 3. The product must not be repaired by a third party
- 4. Wear and tear that affects only the appearance and not the function of the backpack
- 5. Accidental damage
- 6. Damage caused by chemicals or fire
- 7. Damage incurred during air transport
If your issue cannot be covered by the All Mighty Guarantee, you can still contact Osprey; they will offer you a repair of the product for a reasonable price.
|
What is the reasonable lifetime of my backpack? Reasonable lifetime refers to the extent of use you can expect from it. We assess each case individually; a backpack that is used every day will reach the end of its reasonable lifetime sooner than one that is used once a year. |
