I originally ordered the black 15.6” backpack. When I received it, the color/finish was not what I expected. Although the quality and design matched what I was expecting the fabric finish was not to my liking. I sent an email to the seller asking to exchange it for the grey color instead. They sent a replacement which was received 2 days earlier then promised. The grey backpack suited my taste. The finish is a more neutral color which I liked. The quality and feel of the material and zippers feels top notch. Also it has nice padding to protect my delicate laptop during use. The bottom of the backpack has some padding, it’s not just a single layer of nylon fabric. The pocket for the laptop also has extra padding on both sides as well as the bottom. The pocket for a tablet is designed so the bottom is not exposed to impacts at the bottom so it very unlikely your electronics will get damage from impact unless it take an extreme drop. Overall the material feels thick and solid without being too bulky. For the price I paid, this backpack can’t be beat. I really like the hidden pocket in the backpack’s lower padding as well. Just the right size for me to use as an EDC or while traveling. Has a lot of pockets and 3 main compartments. Exactly what I was looking for ultimately. I don’t feel like I am missing any features or quality from picking a Sosoon back compared to the name brand labels out there at a double or triple the cost of this backpack. Also the customer service was exceptional, Thank you Liz from Sosoon who took care of my concerns. I would definitely look to this brand and seller again when I need another backpack. If you are reading this and you are like me trying to find a great everyday back at a reasonable price, this one is it. It’s got a little bit of everything at a great price, and just read all the great reviews like I did. I don’t regret my purchase at all. Sellers like this really explains why Amazon is doing so well.
