Hi, I am seeking a nice protective sleeve for my 13" MacBook. I do have a laptop backpack, but I am looking for a sleeve that I can use to protect my computer when I would carry it in some other bags. The sleeves I've seen so far mostly seem to protect from scratches, not much from exterior shock. Victorinox seems to have a nice protective design, but it seems that they would fit well with 15" laptops. Is there anyone who tried Victorinox sleeve with 13" laptops? Or is there any other products that you would recommend? Thanks!
