Good choice and quality for 80 euros! From a Greek company! Mainly used for hiking, it has plenty of space for a two-day hike with several additional pockets! The waterproof cover is also useful! There are definitely higher quality ones, but you pay more for those!

I have the 35L backpack for about 4 months now (80€), so far it hasn't presented any issues and it holds up well. Obviously, the materials are more budget-friendly compared to similar expensive backpacks from "big" companies. It has plenty of compartments and straps (including one for trekking poles) and satisfactory padding. The clips are okay, the buckles are so-so, I added a layer of fabric tape because the shoulder straps were loosening during the trail and it fixed the problem. It is not waterproof. I wouldn't overload it either. Overall, it is a likable backpack with plenty of features.
