This is one of the more interesting laptop backpacks that I have seen or used. In the past, I used a functional backpack fir travel with my laptop and business gear. Not the greatest looking, but it did serve me well. This Wiersoon Business Laptop Backpack takes it up a notch, largely because it looks more modern, has a more stylish look and has a nice phone charger port accessory.The backpack straps are nicely padded and haveva breathable mesh surface. There is also padding on the back of the pack to give added protection between you and your laptop that fits in a zippered pocket at back. Accessible behind the straps is a pocket behind some of the padding to fit sime items, such as passport, a movel etc. Because of its location access, it is a but more secure.The backpack has a full split open, lockable double zipper for where the laptop goes which helps with travel through airport security. Besides a 15.5" laptop, there are a number of other pockets of various sizes to fit notebooks, pens, charger cables etc. It is not meant for anything very thick. There is also 1 zippered pocket for small stuff.The larger secondary main section has a zippered top effectively. Because of the curves in that particular zipper, I found it a bit harder to close easily. Perhaps after some use it will be smooth. That section is where bulkier items would go. There are no inside pockets in that section. All walls are padded to some degree. That half of the backpack has a durable metal wire frame around it to give a stiffer support.The very front has a small, thin double zippered section with 1 mesh pocket inside.The sides have tall but narrow zippered pockets. I was able to put a standard 500ml water bottle in one side but it was super tight and not practical. Maybe a thin compact umbrella could fit in there. One of them has the standard USB port on the outside with a standard USB-A cable attach inside. You are meant to attach that to a power bank so you can charge your phone while traveling. A useful feature for me.Lastly, there is a large plastic strap handle at the top. Good idea, but the material should have been made of something better than plastic. It cheapens (a small amount), what is otherwise a great looking business backpack. However, given this is only $50 for such a nice pack, I still give it 5 stars.
