This backpack combines a traditional top access with a modern clamshell opening system, offering unprecedented packing flexibility. The square shape ensures maximum space utilization and comfortable carrying thanks to the ergonomically shaped carrying system that can be easily attached or stowed away as needed.
- Double access for perfect organization
The large U-zip opening allows traditional top-down access with a protective overlapping rain flap, while the central 3/4 circumference zip opens the bag like a suitcase, with roll-up dividers separating the contents and a ventilation section at the top allowing wet items to be safely transported without coming into contact with the rest of the contents. - Durable protection from recycled materials
The outer NanoTough™ material is bluesign® APPROVED and made from 100% recycled high-strength nylon with a carbonate coating, which provides exceptional abrasion resistance and high waterproofing, so the contents remain protected even in adverse conditions.

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. |
