Purchased for €25 in February 2024.
The bag is amazing. Sturdy and thick material, you can immediately feel its robustness and durability as soon as you hold it in your hand. It comfortably fits a 15" laptop and has impact protection on the back side. Very practical with its many pockets and the chest strap for difficult situations. In moderate rain while on the bike, it didn't get a drop (I had it on my back). The only drawback I found is in the internal laptop strap, which is made with velcro and doesn't hold well. I would have preferred it with a clip.
Almost a year later and it looks like new.
