In case anyone was wondering about the small sling bag vs. the large belt bag, I figured I’d post a side-by-side pic.

The sling bag is smaller than the belt bag but I liked the small outside zip pocket and the back pocket as well. My stuff fits a little tight in the sling bag but I like that I can keep my keys and phone separate from the rest of my stuff compared to having everything stuffed into my belt bag. The sling bag also has 2 inside pockets, which is great. Now I just hope it comes out in a purple color soon!
