SwissGear 22" Hybrid Laptop Backpack

There is a reason the detail page for the 22" version says it is returned often. I bought the 18" and 22" versions of this bag to try. The 22" bag is only passingly similar to the small bag and it is extremely uncomfortable (I'm a 5'5" woman, average build). I put in the exact same things as I did in the 18" bag, and the 22" bag felt significantly heavier and was 100% more uncomfortable on my back. It felt like a plank against my back. Plus the back panel isn't contoured and doesn't have the breathability that the 18" bag does. The straps also pulled away from the top-back of my shoulders, which obviously isn't great. For someone with a taller/larger build, perhaps this would work. The difference of ~8 liters of space is significant, which was expected, but there is no way I'd want to carry this bag at capacity. I have a backpack with a larger liter capacity and this 22" bag isn't anywhere near as comfortable to put on, even with a partial pack. This bag has compression straps inside, plus there is a compression zipper along the outside, but the pocket situation is very different from the 18". I feel a laptop would be better protected in the 18", because that appears to have better padding. In contrast, the 18" feels like a dream on my back, from the contouring, padding, and overall fit.
