### ⭐⭐⭐⭐⭐ Good Quality, Worth it
*by A***R on 25 June 2026*

good quality as expected, multiple compartments as shown in the images, the material and zips are meet the expected quality as well. good product ..worth the money.

### ⭐⭐⭐⭐ Sturdy but maybe too big
*by A***E on 12 February 2025*

This is by all means a great backpack, sturdy and spacious. It's just too big. About the same size as a carry on luggage. Which I usually like, but there is no waist strap, so the load bearing is 100% on your shoulders and back. At this size it makes it uncomfortable and even a bit painful to carry when full. That being said, I'm a 1.6m woman and not very muscular. The above would probably not be an issue for a big guy.
