Slappa is hard at work trying to revolutionize laptop backpacks and they could actually do it with the introduction of M.A.S.K. The M.A.S.K backpack is unique in that you can choose its outer backpack face and even choose its inner backpack artwork too from a selection of great artist choices. We can’t help but wonder how often you’d actually be able to admire the inside of your backpack, but the selection of artwork they have available is quite nice. M.A.S.K. fits laptops upto 17.5″ and it’s even Fast Scan ready, which means it can go through airport scanners. M.A.S.K. custom build backpacks are retailing for $129.99, but you can use code “CUSTOM” at checkout to get it now for $99 plus free shipping.
