This hk Slim Laptop Backpack is exactly what I've been looking for. Many of my backpacks are big & bulky and fairly heavy once you get everything put into them - I probably carry too much right? This hk Slim Laptop Backpack seems to be very well made with very good and durable materials, the stitching at all the major stress points are very tight. The zippers operate smoothly but they do not overlap so you cannot put a cable securtiy lock through the zippers if you want added security. This thin backpack is very business style-ish and with its padded backboard it is very comfortable against the back. As you can see from my photos, this backpack should be capable of carrying a 16 inch laptop with ease. I put my Galaxy Tab S10 Ultra (14 inch) tablet into the pain compartment pocket with room to spare. There is an additional pocket that will hold my 11 inch tablet or a small notebook as well. This backpack has plenty of pockets and pen holders and does not sacrifice storage space even though it is very thin. The one key thing this has that is a "must" for me is the hidden side pocket that is large enough to hold my pew-pew for off body carry. It holds my P365 or my P365 Macro just fine and I can still zip it shut. I'm not overly keen on the magnetic closure for the very front pocket and would have preferred a more mechanical snap to hold that shut but the magnetic snap does seem to work. I'm still not sure what you can put into the zippered pocket that is on the left shoulder strap but I may put 1-2 packets of my LiquidIV drink mix in there. I really like this hk Slim Laptop Backpack as it checks all of my boxes, it holds quite a bit, empty it is very light, and it has a very good business-look to it.
