Question about Mammut Seon Transporter 25

If I have understood correctly, the Seon Transporter is available in three sizes:
- 15 l / 20 l / 25 l
This is the 25-litre backpack.
This backpack really does hold quite a lot.
I also have the 15-litre laptop backpack for everyday use.
Both are very high quality and robust.

Hello. No. It's too
Well
