The concept of pocket may well be quite laudable, but wants to exploit the existing division of the bag, one comes quickly to a security leak: you're trying to put something in the outer lid pocket, which one would like to have at hand (tempo packets, granola bar or dextrose / pack of gum), the entire lid at the sides bulges to the point where the underlying pen holder on both sides are already outdoors. Hand the next open located under the cover card pouch are (for checks, credit, shopping card, etc.) accessible to a layman easily from outside without opening the lid already! For thieves and pickpockets a unique invitation! Self check-in, as the name advertises used only with caution / prudence. Too bad, because it can be in the large compartment two 0.5-liter water bottles from the supermarket and a small compact camera accommodate, and for other details would be enough space. But because of the ill-conceived cap not recommended for a stroll. So think carefully before buying, if you want to use the card pouch if so, then a no go for this bag!
For the good workmanship and the classification itself I give 3 stars, for the (probably never proven by Tatonka) uncertain cap there but because of the lack of security thick deductions. The case goes back!
