This is my first purchase from this brand, and I'd like to be as specific as possible in this review, especially since I think it deserves 5 stars. Let's start:
• Compact backpack measuring 40x30x13 cm, perfect for taking on flights without having to buy a second carry-on bag;
• It has two external compartments (for smaller accessories like charging cables, SD cards, or notebooks) and one internal compartment (for a tablet up to 11" in my opinion);
• The internal compartments are modular, with a guide for proper installation and extra pieces for possible subdivisions;
• The backpack has excellent padding, both to protect the contents and the back, with padded and perforated material;
• High capacity with minimal bulk; I have others that take up almost twice as much space to have an extra pocket on the back;
• I absolutely loved the waterproof "hood" (see photo), which can be useful not only for rain protection but also to protect the contents while traveling;
• It opens completely thanks to the zippers that push down even after the curve (this is a quality detail as the front part does not "bounce" towards the closure), thus allowing for comfortable use on a flat surface.

Affordable price, quality High, what would I add? There are very small padlocks on the market; I'd use them to lock the hinges at the top for even more security.
But this is a minor detail, I absolutely recommend it!
