The Sinaliy Travel Backpack/Bag has nearly all the features you need for a weekend travel bag. With it compressed, it is the size of a personal item (fits under the seat on the plane) and expanded it may still fit in the personal item box, but definitely in the carryon box at the airport or overhead storage bin on the plane. It is very well padded, particularly the area on your back when used as a backpack. The backpack straps can be detached and stored away in its own zippered compartment when used as a hand bag (carry handle on top and side of the bag). There are a plenty of zippered pockets on this bag including a hidden one on the back of the bag where you can keep you travel documents, phone and other valuable items safe from pickpockets. There is an also a luggage strap on the back of the bag so you can fit it over the handle of of a roller bag for ease of transport. There is a charging port where you can feed you electronics charging cable through to connect to a power bank inside the bag. The clothes compartment zippers open in half for easy packing (there is an outer zipper to expand the clothes compartment to allow for more storage) and as a compression strap to keep your clothes neatly packed. It comes with 2 clear plastic zippered bags for your toiletries to be TSA compliant. The materials seems to be of good quality and craftsmanship for durability. The price of this travel backpack/bag is good as other ones out there with less features can cost more.
