I came across this earlier and thought maybe some of you had seen it before. Anyboody know anything about this? Would it be worth buying to throw in my sons pack? I don't know if he would like it or not and he's kind of rough on gear. I just don't want to get him something that will fall apart when he opens the package. Any opinions?
