I'm planning a budget trip soon and I'm in the market for a tech backpack that can handle my laptop, phone, cables, and a few gadgets without breaking the bank. I haven't traveled much with lots of tech gear before, so I'm wondering if anyone has any recommendations for affordable but reliable backpacks that are also travel-friendly. I'm mainly looking for something lightweight, with good organization, and preferably with some extra security features. Any thoughts or experiences would be awesome—thanks!
