Laptop backpack, which brand is good

There are many brands, sports, Adi, Nike and Puma. Specialized brands are: Jin Shengsi, Tiger Brand, Saber, Belgin and Samsonite. These brands are very famous. Look, you like it. If you like, go to their counter to buy it. Online shopping is also very convenient now. If you install a computer, I suggest you use a double-shoulder computer bag with a vacuum shock-proof interlayer. It seems that the patent of this vacuum shockproof technology belongs to the brand Jin Shengsi. Of course, it depends on which one you like.
