Indeed...I agree with JediForce. In the past I used to have two slingbags and eventually decided to get a backpack. The MicroTrekker looked really cute, and it was adequate at that time, but I am thankful that the final decision went to the MiniTrekker. It's not an overly huge bag, but it has a surprising amount of space inside. That can be used for snacks, a spare T-shirt, plastic bags...and the rear pocket can be used to house a water pack as well if you really want to go 'trekking'.
