It's not the old model with 34L.
It's the new one with 32L and some minor differences.
Very good backpack, it's worth investing in

Amazing backpack
Plenty of space, I might have liked a few more pockets for organization (for example, the middle section has none; maybe with 2 there it would be ideal), but what it has is satisfactory
Comfort is noticeable as soon as you wear it
Durability will show over time
If you often walk for hikes, city trips, day trips, beach... in my opinion, it's worth investing in this one

For the size, it is excellent. It comfortably fits a 15-16 inch laptop in the regular compartment. The 17-inch one can be squeezed in, but not behind the corresponding protective case. It has many extremely useful pockets for cables, power banks, hard drives, and other accessories
