I liked the Mark RydenTag Anti-Theft Backpack I got some much that I decided to order the Mark Ryden Tag II to use as my everyday backpack. This is a softshell bag and a little larger than the Tag. It is anti-theft and has a TSA friendly integrated lock and USB power port. This bag will fit up to a 15.6″ laptop.
