Good balance between heft and portability.
The umbrella's opening and closing mechanisms feel sturdy and work with confidence. I've used some of these umbrellas in the past that has not last more than a few years. This umbrella's build quality gives me some cofidence that it will last for a while. When open, the coverage area is big enough that it can cover both me and my backpack from rain with some light wind. They sure struck a good balance between the size of the umbrella and the portability of it. They also have a lifetime warranty so if it breaks, i'll be sure to get the same thing again.
