MOLNIA 3 in 1 Laptop Backpack, 17.3 inch Computer Bags for Men, Laptop Backpack for Men, for Travel Bussiness Men Women, Black

I chose this over some similar bags because of the expansion zipper. I was looking for something with lots of flexibility and the expansion wasnt offered by other convertible backpacks I found. The material is a sturdy fabric that doesnt provide much structure. For example, they shipped it by folding it in half and putting it in a box. Once you put things in it it holds it shape fine, and the padding provides ample protection since Ill always be carrying it myself. I will most commonly use this as a personal item and haul it around airports by sliding it over the handle of my roller bag. I wanted something more substantial than a 1 strap. The back has openings top and bottom (with velcro closures) for this purpose and it is quite stable used that way. Those openings are to the same compartment used to stow the backpack straps when not in use, so if you slide it onto your roller bag when the backpack straps are stowed the handle has to get past the straps and can even push them out the hole in the top. TIP: I discovered if I tighten the straps all the way I can buckle them to the anchors that have also been stowed in the compartment which reduces the straps freedom to move. This provides some resistance to the straps getting pushed around as much by the roller bag handle. I wish the dual carrying handles were a bit more substantial, but I understand that would make them harder to stow.

I got this computer bag because it had different options on how to carry it—messenger bag or backpack style. Does the job quite well, protects my larger sized laptop and has space for other items as well. Seems to be decent quality. Has a funny smell right after opening the package, but I am sure it will fade over time.

Perfect for traveling. Holds my 15in and 17in laptops on one side and more than enough space on the other side for note books and folders. Plenty of side pockets for smaller things like chargers, cords, etc. All the straps tuck away easily. Would by again!

Works great! Definitely recommend the larger bag if you travel with a secondary monitor!

This backpack is great looking has plenty of zippered compartments but they are a little small except for the two main ones. The capacity was not as good as it appeared in advertising.
