I love this bag. It holds a lot of stuff and has a waterproof design. My favorite part is the zipper pocket on top that can hold your essentials. It's perfect, because you can grab your phone or keys from it without taking the bag off.
Also major style points for being able to clip your U-lock on the outside loops. Good stuff!
Took this backpack on a short Europe trip and was very pleased with its performance. It easily fits into the overhead compartments, feels comfortable, is waterproof, extremely well made and on top of it all - looks super. Used it a couple of times while riding my bike and that too went very well. So yes, highly recommended!
I bought the Chrome Urban EX Rolltop 28 backpack primarily for grocery shopping when I travel by bicycle. I wanted a big, open style bag that can hold a lot of groceries. This backpack does exactly that. It's big, sturdy, holds a lot but manages the weight comfortably well. I was surprised how much weight I can comfortably carry in this backpack. The only negative I can think of, is that it is a big bag and when it is filled, it is higher than my shoulders (I am 6' tall). I need to be extra careful when I try to look over my shoulder in car traffic. Otherwise, I am very satisfied with this backpack.
