You're probably thinking "why would i need a toothbrush and toothpaste in my backpack?" Well, the answer is quite simple: you never know when you are going to have to spend the night somewhere. i am constantly going over to friend's houses and staying the night without planning ahead. so i decided to be proactive and pack a toothbrush and toothpaste wherever i go.
I also decided to put my USB chargers (Car and outlet adapter) as well as my USB battery in this large pocket, because of the many smaller pockets
