Review on 40L Flight Approved Travel Backpack for Men & Women - Vancropak Expandable Carry On Backpack - Lightweight, Water Resistant Business Weekender Bag in Black by Zack Frazier

This backpack exceeded my expectations. The material is really strong, the size is perfect for the maximum carry-on size without being too big. I love that it has the ability to expand, with compression straps both outside and inside. There are multiple zipped pockets inside and out for extra storage. The zippers are amazing, they're very bulky (more so than I've seen on trolleys myself) and they slide so smoothly even into the corners. Hidden backpack straps are perfect for wearing over your head or when you need to check your bag. I'm not too worried about it being black either, as you can easily attach colorful straps/luggage tags or other identifying features to it. to make visible. There are top and side handles for a comfortable grip and they are of excellent quality. I was lucky enough to buy it when it was under $50 and in my opinion it was a steal! Great quality and features for the price!
