1- Uncomfortable,

2- good that you remove the metallic buckle, looks badass but scratch whatever is nearby, not to mention it is heavy, and tossing it to something made of glass, might break it,

3- unless you really tight the bag to your body, the cushing material won't fall into your shoulders,

4- does not come with side strap, but it doesnt matter, the side strap will dig into your arm pit,

5- the bag it is rigid and a nightmare to open the zippers,

6- only have 2 zippers. it would have been nice if would have have one more rear zipper-compartment
