Peak Design Travel Bags

I'd say that's a fair assessment. Its a nice bag, but there are certain things to kinda rule it out of a lot of "travel bag" use cases. Namely the straps and like you said, weight. In my opinion, you have to balance weight versus utility of the compartments and anchors and such, and for me those features make the bag better for how I tend to use it. Weight tends not to bother me as long as the harnesses and straps supporting the weight keep the bag firm and still to my body, and for me that is usually enough. For me personally, it is a great bag for getting from place to place, but not necessarily for long term carry. Also one correction, which I will edit above: the waist straps are in fact padded. Not a significant padding like you'd get in a hiking bag, but enough to make the weight comfortable - its a bit more than the shoulder straps.
