Black and red

umbrella sample that we received for the coming academic year's language promotion - logo and slogan are not added yet.

We all thought this looked attractive if someone holds it walking across the campus to advertise for us. Since it has started to rain in the afternoon (a couple of hours earlier than BBC forecast), I tested this umbrella on the way home. 

But soon I found the problem in its two-layer design - once it is closed and held with the sharp end pointing to the ground, rain on the outer layer will slide down to the top layer which will hold water inside the umbrella. The only way to avoid this is to lay down and open it like the photo. Then it occupies the space.

Can anyone tell me what advantages of this design bring to us, except for its so-called ventilation effect?

I sniffled a lot - thanks for your good wishes!
